``Values of zeta functions at negative integers and the dimensions

of spaces of modular forms"


 Benedict Gross

Euler introduced the zeta function into number theory, and proved a number of beautiful results

on the values of the zeta function at negative integers, using clever techniques to sum divergent series.

I will review the modern theory, which uses analytic continuation to define these values, and relate

the values to the dimensions of certain spaces of modular forms.
