Formal power series solutions with coefficients defined on shrinking discs for some partial differential equations

Analysis of PDEs 2025-12-09 v1

Abstract

In this paper conditions, under which an integro-differential operator is a linear automorphism, are provided. Alternatively, the problem can be considered in terms of existence of a unique formal power series solution for a linear Cauchy problem, where the coefficients of the solution are of a certain Gevrey order on progressively shrinking domains.
