Speaker: Yitang Zhang (University of California, Santa Barbara)  
**Title:** Non-positive sequences in analytic number theory and the Landau-Siegel zero  
**Abstract:**  A number of problems in analytic number theory can be reduced to showing that some related sequences are non-positive. In this direction a typical treatment is based on the idea of the Ʌ2-sieve due to Selberg. We introduce a new approach that may find application to the Landau-Siegel zero problem.
