Abstract: During World War II Hedy Lamarr, a striking Hollywood actress, together with George Antheil, a radical composer, invented and patented a secret signaling system for the remote control of torpedoes.  The ideas in this patent have since developed into one of the ingredients in modern digital wireless communications.  The unlikely biography of these two characters, along with some of the more modern developments in wireless communications will be described.

Bio: Mark is a UBC alum and former math department faculty member. He is most well known for discovering Intersection Cohomology Theory with Robert MacPherson. Intersection Cohomology has had a profound impact on several areas of math, particularly Representation Theory, Algebraic Topology and Algebraic Geometry.
 

About the Niven Lectures: Ivan Niven was a famous number theorist and expositor; his textbooks won numerous awards, have been translated into many languages and are widely used to this day. Niven was born in Vancouver in 1915, earned his Bachelor’s and Master’s degrees at UBC in 1934 and 1936 and his Ph.D. at the University of Chicago in 1938. He was a faculty member at the University of Oregon from 1947 until his retirement in 1982. The annual Niven Lecture Series, held at UBC since 2005, is funded in part through a generous bequest from Ivan and Betty Niven to the UBC Mathematics Department.

Some group cohomology calculations in stable homotopy theory
ESB
Fri 3 Jun 2016, 11:00am-12:00pm

Abstract

 The cohomology of certain p-adic Lie groups plays a central role in chromatic homotopy theory. In this talk I will discuss these groups and discuss some of their elementary group theoretical structure.  Then I will explain some recent group cohomology calculations relevant for stable homotopy theory. In particular I will highlight the result of some highly non-trivial calculation resulting in a surprising isomorphism which cries out for a conceptual explanation.
