Abstract

We prove a precise bound on the number of sections of a pure sheaf on a projective scheme. Our result strengthens the Le Potier-Simpson estimate and generalizes it to schemes defined over a field of any characteristic. This is used to construct the moduli space of semistable sheaves in mixed characteristic via Simpson's method.
