Conserved Quadratic Content and Higher-Spectral Mobility in a Closed Relational Matrix Dynamics

We study the finite-dimensional state space of complex Hermitian positive-semidefinite correlation matrices with unit diagonal for n = 4. We identify a closed matrix dynamics that combines a free commutator sector with an intrinsic correlation-dependent response. The flow preserv...
