DCRP-39: Rank-One Vorticity-Core Decomposition and Burgers-Jet Normal Form

Proves that a spatially common vorticity direction forces axial invariance of the vorticity magnitude, proves a global rank-one Liouville theorem under strictly-DSS sublinear tail growth, and concludes that every nonzero rank-one core must undergo either finite-radius vorticity-direction diffusion or directional tail escape.
