Title: Multiple q-zeta values

Abstract:

Multiple q-zeta values are particular formal power series with rational coefficients in an undetermined variable q. For example, by specializing the parameter q to 1 one obtains multiple zeta values, which are real numbers emerging in various fields like number theory, topology or mathematical physics. We describe recent progress in studying the algebra of multiple q-zeta values.
