Hypermultiplets and Calabi-Yau Compactifications

I will discuss a general formalism to compute non-perturbative corrections to the low energy effective action in Calabi-Yau compactifications with N=2 supersymmetry. I will describe how a detailed analyis of the instanton effects can support some recent conjectures on the quantum structure of the hypermultiplet moduli space.
