Title: Topological epsilon-factors
Abstract: A key property of arithmetic L-functions (that lies at the heart of the Langlands reciprocity) is factorization of the constants in the functional equation into a product of local epsilon-factors. In this talk I will explain a parallel topological construction which provides an epsilon factorization of the determinant of the cohomology of a constructible sheaf. It can be viewed as
an "animation" of the classical Dubson-Kashiwara formula for the Euler characteristics.
