A standard zero-free region for an L-function is a region Re(s) > 1 - log(Im(s))^{-k} for some fixed k>0.
Standard zero free regions had not been known previously for Rankin-Selberg L-functions except in special cases.
This is joint work with Xiaoqing Li.

This is the first talk of the Upstate Number Theory conference, see: http://www.math.cornell.edu/~upstatenumber/index.html
