Ramanujan's conjecture and its generalizations

Zeta (and L) functions are associated with automorphic forms. One of the main themes in the study of the zeroes of these functions, is that of a family. We describe some recent developments, applications and conjectures in the theory. In particular we highlight the role played by symmetry types (from random matrix theory) that are associated with a family. This will then be applied to the generalized Ramanujan conjectures, which we will introduce and discuss in some detail.
