In these lectures I will outline a proof of the Atiyah-Singer Index theorem. I will begin with the definition of the symbol $\sigma_l$ of a linear differential operator $L$ and the notion of ellipticity of $L$. I go on to define the analytic index $i_a(L)$ of a linear elliptic differential operator...more

Course Description: This is a semester course on compact groups with special emphasis on compact connected Lie groups, their structure theory and the theory of representations of such groups. We first prove general results like complete reducibility , Schur's lemma , and orthogonality relations. We...more

Amal Kumar Raychaudhuri (14 Sep 1923 – 18 June 2005) was an Indian physicist, known for his pioneering work in general relativity and cosmology. His most significant...more

In these informal lectures, I shall try to describe the procedure for computing perturbative amplitudes in superstring theory. This can be regarded as a crash course on the subject, primarily for advanced graduate students and post-docs, where I shall skip many derivations but will try to explain...more
