“…Establishing kernel theorems or the related property of nuclearity for a given class of locally convex spaces are therefore questions of great relevance for the analysis of continuous linear mappings on such spaces. The study of these questions for locally convex spaces of functions defined through high time-frequency localization conditions has attracted much attention in recent times [6,7,9,12,13,22,23,25], particularly due to potential applications in the microlocal analysis of pseudodifferential and localization operators.…”
