α′-corrections and their double formulation
Eric Lescano
Abstract
Abstract The present notes are based on three lectures, each ninety minutes long, prepared for the school “Integrability, Dualities and Deformations”, that ran from 23 to 27 August 2021 in Santiago de Compostela and virtually. These lectures, aimed at graduate students, require only a basic knowledge of string theory. The main goal is to introduce α′-corrections to the gravitational sector of different formulations of closed string theory and to reformulate them using novel techniques based on double field theory.
