Variation in families of Riemann surfaces and Hodge structures

Given a (continuous) family of some kind of objects, a first measure of its "variation", or complexity, is given by the minimal number of parameters needed to describe all elements in the family. However, in some cases it is useful to have finer notions of "variation", for example to distinguish between different one-parametric families.

In the talk I will consider the case of compact Riemann surfaces and how their associated Hodge structures can be used to define a notion of "Hodge variation". I will also discuss some results about the existence (or not) of families with "maximal Hodge variation" in certain situations.
