Introductory Lectures on Asymptotic symmetries-1

Abstract: In these lectures, we will look at the subject of asymptotic symmetries and first review the subject in the book "Lectures on the Infrared Structure of Gravity and Gauge theories", by Andrew Strominger. We will first study the Generalized Noether Theorem, which will help us in analyzing the conserved charges of Gauge Symmetries. We will apply this to QED and Gravity in 4 dimensions and describe the abelian gauge symmetries in them. During this discussion, we will also introduce the Infrared Triangle and discuss the idea of memory effect and soft theorem.

Having reviewed the basics, we shall explore the story of Asymptotic symmetries in (even) higher dimensions and discuss the issues one faces while trying to generalize the story in gravity. We will then propose a novel resolution to these issues using some very simple constructs.
