#### Little string theories via F-theory

###### Dave Morrison (UC Santa Barbara, Departments of Mathematics and Physics)

Abstract: Little string theories are UV complete non-local 6D theories decoupled from gravity in which there is an intrinsic string scale. I will present a systematic approach to the construction of supersymmetric little string theories via F-theory. This is joint work with Lakshya Bhardwaj, Michele Del Zotto, Jonathan Heckman, Tom Rudelius, and Cumrun Vafa.

#### Stoilow's theorem revisited

###### Rami Luisto (UCLA)

Abstract: Stoilow's theorem states that any continuous, open and light map from a planar domain to the plane is locally a holomorphic map up to a conjugation with homeomorphisms. From this local fact it follows that up to a homeomorphic change of coordinates a continuous, open and light map between two orientable topological surfaces is a holomorphic map between Riemann surfaces. In this talk we give a modern proof for the local result and, time permitting, discuss how the local result gives rise to the global version.
