Title: An introduction to zeta functions"
Abstract: A zeta function is a function in the complex variable 
defined by a Dirichlet series 
. The first example has been the Riemann zeta function, a kind of prototype for the whole theory. More examples can be generated whenever the 
's count prescribed subobjects of a given structure (e.g., subgroups of index 
in a group, loops of length in a graph ...).

More examples can be generated whenever the 's count prescribed subobjects of a given structure (e.g., subgroups of index in a group, loops of length in a graph ...).The seminar aims at giving an overview on the world of zeta functions and on some of the most common methods used wherein, with a particular emphasis on Group Theory. After a brief introduction on Dirichlet series, the discussion will vary from classical results to more recent developments and works in progress.
