Common-null transport and viscous response from an internal periodic cell: strengthened resolvent estimates and multi-reviewer verification — interim report v0.1

Interim progress report on the study of viscous response from a kinetic model on ℜ3+1×S1 with a common null constraint coupling the observed and internal (circle) directions. Under a two-branch time-reading hypothesis, two signed internal-momentum species (σ=±1) follow an Anderso...

An Open-Loop Endpoint Memory Model for Incompressible Vorticity with a Null-Distance Channel and a Two-Branch Time Plane: Endpoint Response, Non-identifiability, and Numerical Checks

We study a candidate passive extension of the local rotation of an incompressible viscous fluid. The vorticity \(\boldsymbol\omega=\nabla\times\boldsymbol v\) is passed, as a boundary value, to an auxiliary half-line ("null-distance channel") \(y\ge0\) on which a diffusion field...
