Route II: an exact spontaneous-splitting diagnostic 000123 | 000124 | Question: can an invariant quartic select multiplicities without inserting 000125 | a preferred projector? This diagnostic is conditional, not a new TFPT model. 000126 | Assume a nonzero Hermitian endomorphism X of an unmarked complex five-space, 000127 | tr X=0, tr X^2=1. Write its real eigenvalues x_i. Define q=tr X^4. 000128 | We derive the GLOBAL bounds and all equality multiplicities: 000129 | 000130 | 7/30 <= q <= 13/20. 000131 | 000132 | Proof. The constraint manifold sum x_i=0, sum x_i^2=1 is compact and smooth; 000133 | its two constraint gradients are independent. Lagrange multipliers give 000134 | 4 x_i^3-2 lambda x_i-mu=0, so there are at most three distinct eigenvalues. 000135 | One value is impossible. For two values of multiplicities k and 5-k, 000136 | a^2=(5-k)/(5k), b=-k a/(5-k), giving 000137 | q=((5-k)^3+k^3)/(25 k(5-k)). 000138 | This equals 13/20 for k=1,4 and 7/30 for k=2,3. 000139 | 000140 | For three distinct roots a,b,c, the stationary cubic has no squared term: 000141 | a+b+c=0. With positive multiplicities m,n,p summing to five, also 000142 | m a+n b+p c=0. Their common one-dimensional solution is proportional to 000143 | (n-p,p-m,m-n). Enumerating the positive triples (up to permutation:3,1,1 000144 | and2,2,1), excluding coincident roots, gives q=1/2 or1/4. 000145 | Neither reaches the two-value extremes. This exhausts ALL stationary points, 000146 | including spectra with zeros; no block ansatz was imposed. The exact checker 000147 | lists every ordered multiplicity case. Equality at the minimum has spectrum 000148 | (a,a,b,b,b) up to permutations/sign, b=-2a/3. At the maximum: (a,b,b,b,b), 000149 | b=-a/4. Only multiplicities, not a canonical projector, are selected. 000150 | The minimum orbit under U(5) has stabilizer U(2)xU(3). These are internal 000151 | covariance groups; no physical gauge identification is made. 000152 | 000153 | Why boundedness/symmetry does not choose the answer: 000154 | let t=tr X^2 for an arbitrary traceless Hermitian X and use the diagnostic 000155 | polynomials V_sigma=-t+t^2+sigma tr X^4, sigma=+1 or -1. 000156 | For X=r Y with tr Y^2=1: 000157 | V_sigma=-r^2+r^4(1+sigma q(Y)). 000158 | Both quartics are positive at infinity, since 1-13/20=7/20>0. 000159 | Minimizing r gives r^2=1/[2(1+sigma q)] and energy 000160 | -1/[4(1+sigma q)]. Thus sigma=+1 selects the 2+3 orbit and sigma=-1 the 000161 | 1+4 orbit. Sigma=0 has no shape selection. The same unmarked carrier, 000162 | conjugation symmetry, X -> -X symmetry, polynomial degree and boundedness 000163 | admit different preferred splits. A gradient flow with a supplied positive 000164 | metric would make these minima stable modulo symmetry; that metric/flow, 000165 | initial law, fluctuations and thermodynamic limit are NOT derived here. 000166 | No claim that all other stationary solutions are unstable is needed or made. 000167 | 000168 | Assumptions to derive before using this as TFPT: the actual source-generated 000169 | endomorphism X (not the SM Higgs doublet by relabelling), its Hermitian reality 000170 | and tracelessness, invariant contraction, a nonzero broken phase, and the 000171 | effective coefficient of tr X^4 relative to other allowed terms. Without 000172 | X -> -X symmetry, tr X^3 is another independent allowed term. Higher terms 000173 | and constraints could change the result. Positive quartic shape is a precise 000174 | conditional selector; its sign is not a consequence of general stability. 000175 | 000176 | 5. Follow the best-supported route back to the original functional 000177 | 000178 | Route I is first: it identifies the exact missing datum without adding an 000179 | unmotivated field. Derive an actual noncommuting local intervention/product 000180 | from the primitive source, its coherent correlations and its opposite action; 000181 | then apply the ALREADY available quotient/GNS and finite closure theorem. 000182 | Do not repeat GNS as if it selected the alphabet. The new cyclic test shows 000183 | why merely adding 'no hidden degrees of freedom' would not finish this. 000184 | 000185 | The quartic theorem gives a downstream decision criterion, NOT a license to 000186 | choose a potential. For the source's declared profile and an ACTUALLY DERIVED 000187 | linear deformation D(t)=D0+t V, finite-dimensional commuting case: 000188 | [t^4] tr f(D0+t V) = tr(f''''(D0) V^4)/24. 000189 | In a finite bounded holomorphic functional-calculus setting, without 000190 | commutation, it is (2 pi i)^-1 integral f(z) tr[R(z)(V R(z))^4] dz. 000191 | Subtract the corresponding reference coefficient. A nonlinear D(t) adds 000192 | terms involving its higher derivatives. Infinite-dimensional traces, 000193 | domains and regularization require their own proof; no unjustified integral 000194 | formula for the unbounded physical source is asserted. 000195 | 000196 | Even a positive profile does not force a positive fourth derivative: 000197 | for f(x)=exp(-x^2), f''''(0)=12 and f''''(1)=-20/e. The eta piece is not a 000198 | positive real quartic potential. Reflection positivity is a condition on 000199 | correlation kernels, not a rule assigning +tr X^4 to an unknown field. 000200 | Therefore the checked original seed at302-343 neither supplies V nor 000201 | identifies this coefficient with a positive invariant on an unmarked C5. 000202 | Known E8 quartic root invariants act on other already specified spaces; 000203 | without an equivariant source map they cannot substitute for this datum. 000204 | 000205 | Success criterion for the next source derivation: 000206 | one common primitive operation/product law must provide (i) the allowed 000207 | coherent local operations and their correlations, and (ii) its actual field 000208 | deformation/effective invariant. Then the current theorems test algebra 000209 | uniqueness and 2+3 stability without inserting either answer. New independent 000210 | axioms must be labelled as such. At present no previously assumed physical 000211 | input has been discharged; what is eliminated is the need for a prescribed 000212 | 2+3 projector WITHIN the positive-quartic conditional diagnostic. 000213 |
