On weighted inductive limits of spaces of ultradifferentiable functions and their duals

Abstract: In the first part of this paper we discuss the completeness of two general classes of weighted inductive limits of spaces of ultradifferentiable functions. In the second part we study their duals and characterize these spaces in terms of the growth of convolution averages of their elements. This characterization gives a canonical way to define a locally convex topology on these spaces and we give necessary and sufficient conditions for them to be ultrabornological. In particular, our results apply to spaces of… Show more

“…The present section is devoted to developing a framework for the STFT of general ultradistributions with respect to compactly supported ultradifferentiable window functions of Beurling type. Our analysis closely follows that from [4, Section 2] (see also [3,Subsection 2.3]), though a bit more precision will be needed. Throughout this section we will always assume M p satisfies pM.1q, pM.2q 1 , and pM.3q 1 .…”
