A Riemann-Hurwitz Theorem for the Algebraic Euler Characteristic

Published 3 Oct 2015 in math.AG | (1510.00863v4)

Abstract: We prove an analogue of the Riemann-Hurwitz theorem for computing Euler characteristics of pullbacks of coherent sheaves through finite maps of smooth projective varieties, subject only to the condition that the irreducible components of the branch and ramification locus have simple normal crossings.
