Title: What happens when a period vanishes?
Abstract: A period is a number obtained by integration of an algebraic
differential form over a topological cycle. In this talk I will review
few phenomena which follow from the vanishing of periods. This includes
the arise of limit cycles in planar differential equations, contraction
of curves and the millennium Hodge conjecture.
