**Date & Time:** November 8, 2010; 14:30-15:20.

**Venue:** Ramanujan Hall

**Speaker:** Sarang Sane, TIFR Bombay

**Abstract:** In continuation with the previous talk, we will prove
Serre's theorem linking the Euler characteristic of the Koszul
homology and the multiplicity. If time permits, we will define
the multiplicity symbol (possibly a slightly generalised notion
of it) and then aim to link it up with the previous results.
