MPI-Oberseminar A multiple zeta value (MZV) is a real number specified by a string of positive integers.

The sum of the string is the weight, and its length is the depth. MZVs of depth one are

just values of the Riemann zeta function at positive integers; MZVs of depth two were

already studied by Euler. MZVs of arbitrary depth became a hot topic in the early 1990s

with their simultaneous appearance in perturbative quantum field theory and knot

theory. Since then the field has continued to develop rapidly. I will describe various

results about MZVs and their relatives, such as alternating ("colored") MZVs and multiple

t-values.
