Analytic Singular Support Properties for Integral Operators in Hyperfunctions

Abstract

In this paper, we continue our study of integral operators in [12] and give a result on the analytic singular support of the kernel hyperfunction similar to the main result in [12]. A new feature with respect to [12] is that we use classes of ultradifferentiable functions associated with a weight function and a topological description of related spaces of quasi-analytic functionals.
