A Paley-Wiener theorem in extended Gevrey regularity

Functional Analysis 2019-01-04 v1

Abstract

In this paper we introduce appropriate associated function to the sequence Mp=p\tp\sM_p=p^{\t p^{\s}}, pNp\in \N, \t>0\t>0, \s>1\s>1, and derive its sharp asymptotic estimates in terms of the Lambert WW function. These estimates are used to prove a Paley-Wiener type theorem for compactly supported functions from extended Gevrey classes. As an application, we discuss properties of the corresponding wave front sets.
