Brylinski-Radon transformation in characteristic
arXiv:2307.04156
Abstract
In this article, we characterize the image of the Brylinski-Radon transform in characteristic via Beilinson's theory of singular supports. We also provide an alternate proof of Brylinski's results over , which also works for sheaves with finite coefficients. Along the way, we also obtain a microlocal criterion for the descent of perverse sheaves which could be of independent interest.
