First lecture of the _MINI-COURSE on __Quantum Black Holes for 
Mathematicians_

By Atish Dabholkar (ICTP, HECAP)

Description of the course:  Study of black holes in string theory has 
revealed a beautiful and precise connection between the physics of 
quantum black holes and topics in number theory and geometry. The aim of 
these lectures is to outline these connections through examples starting 
with basic concepts and motivations from physics.

_BASIC NOTIONS SEMINAR
_
by Don B. Zagier  (MPI, Bonn/ICTP)

Title:
What are the Betti numbers of a manifold?

Abstract:
We will show how this innocent-sounding title leads to some non-trivial 
questions of both topology and number theory.
