TITLE   Introduction to Double Field Theory and applications to cosmology
ABSTRACT

  String theory predicts a unique extension to general relativity (GR) which is naturally described by Double Field Theory (DFT). This lecture series will provide a self-contained introduction to DFT and its cosmological applications. As a preliminary motivation, we will provide a basic overview of key aspects of string theory, aimed at a general audience (Lecture 0). We will then introduce the basic formalism of DFT as a natural extension of GR (Lecture 1). Following this, we will turn to cosmology and show how DFT extends the Friedmann equations of GR (Lecture 2), before discussing cosmological solutions as well as challenges in constructing de Sitter vacua, akin to recent Swampland conjectures (Lecture 3).
