Instanton corrections and emergent strings

We study limits of infinite distance in the moduli space of 4d N = 2 string compactifications, in which instanton effects dominate. We first consider trajectories in the hypermultiplet moduli space of type IIB Calabi-Yau compactifications. We observe a correspondence between towers of D-brane instan...

We first consider trajectories in the hypermultiplet moduli space of type IIB Calabi-Yau compactifications.
