Entropy as a functor
Tobias Fritz , Perimeter Institute

Area: information theory and mathematics

Abstract:

Shannon entropy is of one the most useful concepts in applied mathematics. I will explain how it can be regarded as a functor on the category of finite probability spaces, and how this can be turned into a characterization of Shannon entropy. This is joint work with John Baez and Tom Leinster.

Biography of Speaker:

Tobias Fritz received his doctorate from the Max Planck Institute of Mathematics, Bonn, Germany, has been a post-doctoral fellow at the Institute of Photonic Sciences, Barcelona, Spain, and has now joined the Perimeter Institute for Theoretical Physics in Waterloo, Canada.
