4. Black Hole Microstate Counting (Speakers - Subhodip Bandyopadhyay and Sourav Maji)

(I) Please find Subhodip Bandyopadhyay's lecture 2 (Click Here ) and lecture 3 (Click Here ) notes here.

For an introduction to superstrings, the simplest reference will be the book by Becker, Becker and Schwarz. 

For D branes, a great reference will be vol.1 of Polchinski's book and also his lecture note on D branes (Click Here).

Here is a good review of magnetic monopoles in KK theories by Gross and Perry. Click Here to get it.

(II) First three lectures cover some basics of string theory, superstrings , T duality and D-brane. 

Understanding microscopic origin of Bekenstein-Hawking entropy is one of the most important problem in string theory. It will be very interesting to know how can we relate a geometric quantity to a counting problem. 

Sourav Maji will derive the Bekenstein-Hawking formula from microstate counting. 

He will do it for two cases: 

(1) For N=4 supersymmetric black hole and 

(2) For N=8 pure D-brane black hole, where the black hole is described as pure D-brane configuration. 

Out of the remaining three lectures, he will try to cover the N=4 case in the first two lectures and in the last lecture, he will talk about the N=8 counting in an alternative approach.
