On Kolmogorov entropy compactness estimates for scalar conservation laws without uniform convexity

Fabio Ancona, Olivier Glass, Khai T. Nguyen

In the case of scalar conservation laws $$u_t+f(u{)}_x=0,t\ge 0,x\in \mathbb{R},$$ with uniformly strictly convex flux $f$, quantitative compactness estimates - in…
