Relative subanalytic sheaves II

Algebraic Geometry 2021-07-20 v3

Abstract

We give a new construction of sheaves on a relative site associated to a product X×SX\times S where SS plays the role of a parameter space, expanding the previous construction by the same authors, where the subanalytic structure on SS was required. Here we let this last condition fall. In this way the construction becomes much easier to apply when dimension of SS is bigger than one. We also study the functorial properties of base change with respect to the parameter space.
