Behavior Change as a Psychological Enterprise

Deborah Prentice
Visiting Professor, Institute for Advanced Study

Solving societal problems involves changing people’s behavior – inducing them to drink less, exercise more, turn down the heat, stay in school, and so on. Interventions designed to change these behaviors have met with limited success. School of Social Science Visiting Professor Deborah Prentice discusses how a closer look at interventions and their affect on people’s thoughts, feelings, and motivations reveals why some succeed and others fail, and she also suggests strategies for improving these outcomes.

CSDM - On P vs NP, Geometric Complexity Theory, and the Riemann Hypothesis

Ketan Mulmuley

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.
