Vanishing of cohomology in infinitely ramified towers
arXiv:2605.27188
Abstract
We give a new proof of vanishing result of Esnault for the cohomology of constructible sheaves in the tower of ``mock'' Frobenius covers of projective space. The key idea is to use (a global form of) the perversity of nearby cycles.
