Let $u$ be a solution to a weakly hyberbolic semilinear partial differential equation with real analytic Cauchy data. The main result of the paper asserts that if $u$ is assumed to be in a Gevrey space close enough to the space of analytic functions, then it is analytic.

Abstract
Let $u$ be a solution to a weakly hyberbolic semilinear partial differential equation with real analytic Cauchy data. The main result of the paper asserts that if $u$ is assumed to be in a Gevrey space close enough to the space of analytic functions, then it is analytic.File in questo prodotto:
