### Course Syllabus

#### Abstract

In this seminar we will cover the basics of the theory of elliptic operators, examples of which include the de Rham and Dolbeault operators, as well as their generalisations such as the Dirac operator. We will explain how several seemingly unrelated results in geometry and topology (e.g. the Hirzebruch and Rokhlin signature theorems and the Riemann-Roch theorem) all follow from the general index formula by M. Atiyah and I. Singer, and sketch a proof of the latter.

#### Learning Objectives

• Learn the basic theory and classical examples of elliptic differential operators, as well as related techniques and ideas
