Abstract: The talk will give an introduction to results of Kollar, based
on earlier work of Lieblich and Olsson, showing that the underlying
Zariski topological space of a variety determines the variety, under suitable hypotheses. I will try to state results in some generality, and sketch proofs under some extra simplifying hypotheses, which will however show the main new features.
