Abstract:

In this paper we prove a conjecture by P.-L. Lions on maximal regularity of $L^q$-type for periodic solutions to $-\Delta u +
Du
^\gamma = f$ in $\mathbb{R}^d$, under the (sharp) assumption $q > d \frac{\gamma-1}\gamma$.

Keywords: maximal regularity, Kardar-Parisi-Zhang equation, Riccati equation, Bernstein method
