Ordering has a coherent effect, 000163 | but only through this central phase. It is not a nonabelian logical 000164 | five-code interaction. For disjoint supports the local symplectic form 000165 | vanishes. No physical time or clock calibration is read from the order. 000166 | 000167 | On the neutral Fock module zero modes act0. In normalized oscillator 000168 | coordinates, let alpha be the total nonzero-mode displacement, which is 000169 | square-summable by smoothness. The Bargmann form is 000170 | 000171 | D(alpha)P(z)=exp(-||alpha||^2/2) exp(alpha.z) P(z-bar(alpha)). 000172 | 000173 | If alpha!=0 and P is a nonzero finite polynomial, the right side cannot 000174 | be a finite polynomial: restrict to a line in a nonzero displacement 000175 | coordinate, with the other coordinates fixed so P is notzero, and use 000176 | the exponential factor. The same argument applies with infinitely many 000177 | available modes because the input polynomial uses finitely many and 000178 | some displacement coordinate is nonzero. 000179 | Therefore no nonzero finite Fock polynomial is sent to a finite Fock 000180 | polynomial by a nonzero displacement. In particular an exactly 000181 | code-preserving endpoint of ANY such finite Cartan-Weyl history must 000182 | have alpha_total=0 and acts only as a common phase on the neutral code. 000183 | Individual profiles may be nonzero and cancel; constant-profile zero 000184 | modes are also trivial here. Nontrivial means the TOTAL oscillator 000185 | displacement, not a single chosen pulse. 000186 | 000187 | This all-history statement is analytic, not inferred from truncating an 000188 | exponential or enumerating finite profiles. It excludes R5/P2 selection
