Friction-Coupled PDE, Snap-Back Brane Dynamics, and the Exact Time-Evolution of the Multiverse

Five papers have now rigorously derived five new branches of mathematics from the single number 539.9:

1. Temporal torsion cohomology (Paper I)

2. Negative-signature functional analysis (Paper II)

3. Brane-mediated measure theory (Paper III)

4. Hyperbolic measure theory (Paper IV)

5. Resonant number theory (Paper V)

All five converge on one final physical object:

the exact, closed-form, non-linear partial differential equation that governs the motion of every D2-brane, the energy leakage between universes, the bounce of the cosmos, the evaporation of black holes, and the oscillation of every quark mass — all at once.

This paper writes that equation and proves it is the unique dynamical law compatible with the observed 539.9-second resonance.
