Upper bounds of nodal sets for Gevrey regular parabolic equations

Analysis of PDEs 2026-02-17 v2

Abstract

We consider the size of the nodal set of the solution of the second order parabolic-type equation with Gevrey regular coefficients. We provide an upper bound as a function of time. The dependence agrees with a sharp upper bound when the coefficients are analytic.
