Abstract
We show that the strongest Gevrey irregularity of kernels to positive semi-definite operators appear at the diagonals. We also prove that positive elements with respect to the twisted convolution, belonging to a Gevrey class of certain order at the origin, belong to the Gelfand–Shilov space of the same order. In the end we apply these results to positive semi-definite pseudo-differential operators.
