Let $k=1$, let $u_0\in H^s(\mathbb{R})$ with $s>3/2$, and let $u$ be the corresponding solution of equation (8.0.1), with lifespan $T$. Finite-time wave breaking conjecture. The so…

Breaking-dynamics conjecture. All, or at least most, even initial data characterized by zero initial velocity and a single vacuum point in the density should follow a similar break…

Global existence and wave-breaking conjecture. If
