Zeta functions for finitely generated groups

This talk discusses spectral properties of ``non-commutative" crystal
lattices. After giving a quick survey of twisted Laplacians, we shall
take a look at spectral aspects of Cayley graphs associated with finitely generated groups. The notions of cogrowth, zeta functions, and Ramanujan graphs are handled.
