Its same-face q/p 000008 | blocks are the original smoothing cross-face kernel X_q=(2cosh(ell h_q))^-1 000009 | followed by the inverse geometric map. This is a genuine positive source 000010 | connection, with fixed endpoint, spin and coefficient factors. It is not 000011 | a freely fitted dual character or an additional common CAR covariance. 000012 | 000013 | The resulting two-field responses are computable in the given source. 000014 | Their promotion to the original structural Yukawa or closed CP reader is 000015 | a distinct operator statement. The whole C3 image also gives a decisive 000016 | test for any proposed rho insertion, stated below with the TOTAL Hom action. 000017 | 000018 | 1. Use the entire already given source and its actual geometric map 000019 | Let H_q and H_p be the full charged boundary coefficient spaces on one face, 000020 | including all actual finite slots. Put K_q=H_q+H_q and K_p=H_p+H_p. 000021 | The existing charged covariance is 000022 | G_q=[[A_q,X_q],[X_q,I-A_q]], 000023 | A_q=(I+exp(-2ell h_q))^-1, X_q=(2cosh(ell h_q))^-1. (1) 000024 | The symbols A_q here denote the graph occupation, not the differential 000025 | connection in h_q. No occupied or unoccupied quarter modes are discarded. 000026 | 000027 | The proved whole source transport has the form 000028 | J:K_q -> K_p, J=Swap tensor j, 000029 | j=i0 gamma_F F_R R_x, j h_q j^-1=-h_p, 000030 | J G_q J*=G_p. (2) 000031 | Its actual G/W frame factors, quarter carry, C_faces and closed transported 000032 | domain are already proved. They are reused, not replaced by a fiber matrix. 000033 | 000034 | There is consequently ONE specified reverse comparison operator 000035 | B_qp=G_q J*:K_p -> K_q. (3) 000036 | Its blocks are exactly 000037 | B_qp=[[X_q j*,A_q j*],[(I-A_q)j*,X_q j*]]. (4) 000038 | In particular B_qp^(00)=B_qp^(11)=X_q j*. The geometrical face swap in J 000039 | is essential: it is why these components are the original crossing 000040 | coherence, rather than a newly postulated mixed occupation. 000041 | 000042 | 2. Actual kernel composition in the G/W charts 000043 | On regular lifted arcs write the ALREADY FIXED maps as W_q,W_p. Their 000044 | pointwise factors include 3^-1/2 sqrt(pi'), the explicit G^-1, and the 000045 | original spin phase, metric and analytic continuation. Define 000046 | Gtilde_q=W_q,faces G_q W_q,faces*, 000047 | Jtilde=W_p,faces J W_q,faces*. 000048 | The entire transported reverse kernel is thus exactly 000049 | Btilde_qp=Gtilde_q Jtilde*=W_q,faces B_qp W_p,faces*. 000050 | For boundary variables u,v and their given half-density measures, 000051 | Btilde_qp^(ij)(u,v) 000052 | =sum_k integral Gtilde_q^(ik)(u,t) Jtilde^(jk)(v,t)* dt. (5) 000053 | For the geometric local spin pullback in Jtilde, the integral evaluates to 000054 | Gtilde_q^(i,1-j)(u,R^-1 v) jtilde(v)*, (6) 000055 | with the actual pullback half-Jacobian in jtilde. Equation (5), rather 000056 | than a bare coefficient matrix, fixes all endpoint and density factors. 000057 | The reverse kernel maps the p fiber at v to the q fiber at u. It does NOT 000058 | mean that the p packet is the second independent radial face. 000059 | 000060 | On the charged conjugate slots the complete covariance is I-bar(G_q). 000061 | Its reverse comparison is (I-bar(G_q))bar(J)*; the same-face component 000062 | is -overline(X_q j*). This is fixed by T_faces and retains the entire 000063 | selfdual source. An ordinary trace over normal components is not silently 000064 | identified with a charged neutral-field observable. 000065 | 000066 | 3. Why (3) needs no new joint state 000067 | For the convention omega(a*(f)a(g))=, put the p notation for the 000068 | SAME field equal to a_p(g)=a_q(J* g). Then its cross matrix element is 000069 | omega(a_p*(f)a_q(g))=. 000070 | The whole block of such comparisons is positive, but its CAR metric on 000071 | K_q+K_p is [[I,J*],[J,I]], not diag(I,I). In the ACTUAL source take any 000072 | nonzero v in Ran(G_q). The cross block acts on (v,Jv) with eigenvalue2. 000073 | It cannot be called a covariance of two independent CAR copies with 000074 | identity metric. Quotienting the 000075 | redundant labels gives exactly the old one-source field space. No new 000076 | Gaussian premise or common state is being inferred from a rectangular map. 000077 | 000078 | 4. Pairing with the actual K-valued mu, without losing a weight 000079 | RHO-DUAL-COEFFICIENT-HOM-REVIEW.txt proves 000080 | mu in K_C tensor Hom(Fq,Fp) 000081 | using the original normalized beta:(L_a)^2 -> O. This is now paired with 000082 | the actual reverse Hom in (5). At matched endpoints the coefficient part 000083 | tr_Fp(mu(u) B_qp(u,u)) (7) 000084 | is well typed: the intermediate Fq and Fp fibers cancel in the right order. 000085 | It still has the displayed differential/spin-density weight. It is not 000086 | automatically a dimensionless scalar simply because the Hom trace exists. 000087 | 000088 | Use the GIVEN boundary half-density pairing and the original tangent or 000089 | Clifford contraction of the insertion being evaluated. For example, in a 000090 | fixed arclength trace chart mu|boundary=mu_tau ds; a neutral scalar-current 000091 | reader uses mu_tau, whereas the boundary Clifford product N c(mu) uses 000092 | i0 Z mu_tau (or its specified selfadjoint normalization). These are different 000093 | operators. The source's N, c and metric determine their factors when that 000094 | reader is specified. This review neither chooses between them nor treats 000095 | the raw K-valued mu as a dimensionless multiplication operator. 000096 | 000097 | Denote an actually specified contraction H_q -> H_p by M_mu. With bounded 000098 | smearing on regular arcs the given same-face response is the genuine 000099 | finite number 000100 | A_mu=Tr_Hp(M_mu X_q j*)=Tr_Hq(j* M_mu X_q). (8) 000101 | Here X_q is trace class for the existing one-dimensional elliptic h_q with 000102 | smooth bounded finite coefficients; its exponential spectral decay proves 000103 | this analytically. Unitary j and W preserve trace class. The regular-arc 000104 | statement suffices without assigning an unproved global multiplier domain 000105 | to a new reader at branch vertices. If that reader's transported closed 000106 | domain is already supplied, use that domain, with no new extension choice. 000107 | The complete boundary contraction must use (5) and the given pairing, so 000108 | no square-root Jacobian, conjugate spin factor or endpoint is omitted. 000109 | 000110 | For the WHOLE actual mu, do not replace that qualification by a bounded 000111 | multiplier claim or select new cutoffs. At an original ramification point 000112 | z-z_j~u^3 its flat differential is generically a nonzero constant times du. 000113 | The actual base tangent coefficient consequently has behavior 000114 | m_mu~u^-2~|theta-theta_j|^-2/3. 000115 | The two W half-form factors cancel in the multiplication conjugacy; they 000116 | do not remove this norm singularity. This coefficient is L1 but generically 000117 | not L2. Multiplication by it after a smoothing operator need not be an L2 000118 | operator if the output is nonzero at the mark. Thus (8) is NOT an automatic 000119 | Hilbert-space trace for the complete unsmeared original insertion. 000120 | 000121 | The original smooth crossing kernel nevertheless supplies its finite 000122 | DIAGONAL FORM PAIRING, with no newly selected smearing: 000123 | A_mu^form=integral tr[m_mu(theta) 000124 | (X_q j*)(theta,theta)] dtheta. (8a) 000125 | The L1 singularity and bounded smooth kernel prove absolute local 000126 | integrability at all four marks. The coefficient metric and spin factors 000127 | are the ones in (5), not a Euclidean raw Fuchs row norm. This is a typed 000128 | source-kernel form response. A physical unbounded CAR composite or an L2 000129 | trace-class realization still has to use the actually given domain rule; 000130 | it is not supplied by calling the integrable diagonal form an operator. 000131 | 000132 | 5. The TOTAL cubic test of the proposed response 000133 | The actual coefficient descent has delta_q=Pc,q c*, delta_p=Pc,p c*, 000134 | with delta_q W_q=W_q, delta_p W_p=W_p. The map J intertwines them and 000135 | the transported covariance commutes with them. The typed Hom actions are 000136 | delta(M)=Pc,p (c*M) Pc,q^-1 for M:Fq -> Fp, 000137 | delta(B)=Pc,q (c*B) Pc,p^-1 for B:Fp -> Fq. (9) 000138 | Their intermediate factors cancel in the trace. These directions must 000139 | not be interchanged. They include all coefficient signs, not only a naked 000140 | geometrical differential or a scalar native family-center phase. 000141 | 000142 | Consequently, if an insertion M_chi has character chi under this FULL 000143 | natural action and its tangent/Clifford contraction is covariant, then on 000144 | the given test domain its compression satisfies 000145 | W_p* M_chi W_q=chi W_p* M_chi W_q. (10) 000146 | For the complete singular multiplier this equation is an identity of its 000147 | integrable forms, not an unproved L2 operator identity. For chi!=1 that 000148 | form compression is zero. Averaging the three sheets keeps only 000149 | (M+delta M+delta^2 M)/3. Since J and X_q are equivariant, the whole form 000150 | pairing (8a), or (8) when its stronger domain premise holds, has the same 000151 | selection. This does not require adding a cutoff to the original source. 000152 | 000153 | The calibration to the ORIGINAL lift is concrete. The normalized f_a and 000154 | beta in the Hom report obey c*f_a=f_(a-1), so the square trivializations 000155 | carry no extra cubic phase. Applying the old R product map twice gives 000156 | exactly this c pullback on both coefficient ends. Its two spin-central 000157 | minus signs cancel. Changing from (L0,L1,L2) to G's actual (L0,L2,L1) 000158 | order only conjugates the coefficient matrices. Thus c=R_V^2 on the 000159 | actual Voff product representation is the natural Hom action in (9), 000160 | including its differential factor. The Pc factors express that action; 000161 | they are NOT an extra second multiplication of its character. 000162 | 000163 | Hence the rho line has chi=rho^2=omega under the full action. Provided 000164 | the proposed boundary reader really intertwines that SAME action, (10) 000165 | annihilates its insertion in the fully descended source. This is a 000166 | testable condition, not an assumption that every reader has that action. 000167 | The two c orbits on the six off-diagonal products have length three, so 000168 | their invariant space has rank2. The total mu family also has invariant 000169 | components; this does not annihilate the full family, its norm or the 000170 | whole F5 kernel. 000171 | An additional compensating ACTUAL reader/endpoint leg, a marked open arc, 000172 | or a different original sewing consumer changes this test. A reverse Hom 000173 | frame by itself is not such an extra selected character: it is already 000174 | included in (9). No exclusion of all physical rho channels follows. 000175 | 000176 | 6. Compare the actual original sewing and original output consumer 000177 | Directly read fullv21 introduction:198-205,225-251 and its seam appendix 000178 | 006:346-366,007:1-22. They prescribe FOUR cut pieces C1,C2,Gamma_+,Gamma_-, 000179 | APS on C1,C2, and a unitary phase U_Gamma=e^(i theta) on the seam pair. 000180 | The seam operation is real original data. These passages do not give the 000181 | specific trace formula identifying Gamma_+/- with the two F5 faces and 000182 | the q/p R-related endpoints, including their coefficient/spin frames. 000183 | The appendix's U_Gamma^2=I can mean the WHOLE two-way matching, whose 000184 | return uses the inverse unitary; it does not alone prove a pointwise 000185 | angular reflection or identify the bare multiplier with an involution. 000186 | 000187 | At fixed ungauged endpoint labels, j* M_mu is supported on the R graph, 000188 | whereas the actual original finite one-form qM is multiplication on the 000189 | diagonal. A nonzero test field in an arc disjoint from its R image detects 000190 | this difference immediately. This excludes their DIRECT equality in those 000191 | labels. It is no general locality obstruction: original seam gluing can 000192 | identify the two arcs, and eliminating the bulk can turn a local variation 000193 | into a nonlocal boundary response. Both effects must use their original 000194 | endpoint/Poisson maps, not a new arbitrary p species or fitted kernel. 000195 | 000196 | The first concrete equality to check for such a seam realization is 000197 | T_- psi(theta)=U_Gamma(theta) F_Gamma(theta) 000198 | T_+ psi(b_Gamma(theta)), (11) 000199 | with T_+/- the actual original trace maps. Comparing its b_Gamma and 000200 | F_Gamma with (5)-(6) decides whether (8) is a local insertion on the glued
