Title: Modularity and Fibrations in Mirror Symmetry

Abstract: We will introduce appearances of modularity in the study both of families of Calabi-Yau threefolds and of their enumerative invariants.  An important role is played by the structure of fibrations and the DHT fibration-degeneration mirror correspondence, which clarifies how these notions of modularity are (and are not) related.  This is joint work with Boris Pioline and Thorsten Schimannek.
