Speaker: Fan Chung (University of California, San Diego) Title: Sequences: random, structured or something in between Abstract: There are many fundamental problems concerning sequences that arise in many areas of mathematics and computation. Typical problems include finding or avoiding patterns; testing or validating various ‘random-like’ behavior; analyzing or comparing different statistics, etc. In this talk, we will […]

Speaker: Zhengwei Liu (Harvard Physics) Title: A new program on quantum subgroups Abstract: Quantum subgroups have been studied since the 1980s. The A, D, E classification of subgroups of quantum SU(2) is a quantum analogue of the McKay correspondence. It turns out to be related to various areas in mathematics and physics. Inspired by the quantum McKay correspondence, […]

Speaker: Don Rubin (Harvard Statistics) Title: Essential concepts of Causal inference—a remarkable history Abstract: I believe that a deep understanding of cause and effect, and how to estimate causal effects from data, complete with the associated mathematical notation and expressions, only evolved in the twentieth century.  The crucial idea of randomized experiments was apparently first proposed in 1925 in the context of […]
