The universal geometry of heterotic vacua (part 2)

In this continuation of the talk we aim to describe in more detail how features of the deformation theory are captured by the extended geometry defined in part 1. The universal geometry of (integrable) complex structures is chosen as an example.

We will also see how this formalism allows us to gain a better understanding of the N=1, d=4 effective field theory by discussing the role of the extended spin connection in the kinetic term for moduli fields.
