Conormal distributions in the Shubin calculus of pseudodifferential operators (1702.03111v1)
Published 10 Feb 2017 in math-ph, math.AP, and math.MP
Abstract: We characterize the Schwartz kernels of pseudodifferential operators of Shubin type by means of an FBI transform. Based on this we introduce as a generalization a new class of tempered distributions called Shubin conormal distributions. We study their transformation behavior, normal forms and microlocal properties.
