Title Of Talk: Combinatorial zeta and L-functions

Abstract: Zeta functions are counting functions in nature. For instance the Dedekind zeta function for a number field counts integral ideals, the zeta function for a variety defined over a finite field counts solutions in finite extensions of the base field, while the Selberg zeta function counts closed geodesics in a compact Riemann surface. In this talk we shall discuss the analogue of zeta and L-functions in combinatorial setting, that is, attached to graphs and higher dimensional simplicial complexes. Similarities and dissimilarities between number theoretic and combinatorial zeta functions will also be compared.
