This series of three talks will give a nontechnical, high level overview of geometric complexity theory (GCT), which is an approach to the P vs. NP problem via algebraic geometry, representation theory, and the theory of a new class of quantum groups, called nonstandard quantum groups, that arise in this approach. In particular, GCT suggests that the P vs. NP problem in characteristic zero is intimately linked to the Riemann Hypothesis over finite fields. No background in algebraic geometry, representation theory or quantum groups would be assumed. References for GCT: The basic plan of GCT is given in: GCTflip: "On P vs. NP, Geometric Complexity Theory and the Flip I: high level view". It has been partially implemented in a series of papers: GCT1 to GCT11. GCT1 to 4: Joint with Milind Sohoni GCT5: Joint with Hari Narayanan GCTflip, its abstract (GCTabs), and GCT1-8 are available on the speaker's personal home page. GCT8-11 are under preparation.     Lecture Notes 539 KB Lecture Notes (.ps) 708 KB
