Title:
The Tau of Ramanujan

Abstract of Talk

The sequence of numbers 1, -24, 252, -1472, 4830, ... was extensively
studied by the great Indian mathematician Ramanujan almost a century ago.
These numbers - the values of Ramanujan's tau-function - have been the
guiding force behind several themes in Number Theory. They continue to
tantalize us with easy-to-understand problems some of which are still open
today. This talk will be a relaxed introduction to these numbers and is
meant for a general audience.
