Diffusion stabilises time-periodic solutions in conservation laws coupled to a relaxation oscillator

What the math gives to ML

The paper gives a constructive mechanism for stabilizing relaxation-type dynamics: a fast variable evolves on an S-shaped critical manifold while a positive diffusion operator damps spatial or modal perturbations. Its useful transferable asset is the separation between slow motion, fast jumps, and a spectrally stabilizing dissipative term, together with explicit fold-layer scalings such as $\eta^{1/3}$ and $\eta^{2/3}$. A neural implementation should therefore use a recurrent or state-space block with learned slow-fast vector fields and diffusion applied specifically to the fast hidden state, rather than adding undifferentiated noise or weight decay. The main falsifiable prediction is improved long-horizon stability and convergence to a reproducible periodic or attractor regime at similar parameter count.
