My Thursday Colloquium talk

board On the 9th of January 2014 I will be giving a talk at the Algebra and Geometry of Modern Physics seminar here in Warsaw.

Title “What the functor is a superfield? ”

Abstract Physicists are usually quite happy to formally manipulate the mathematical objects that they encounter without really understanding the structures they are dealing with. It is then the job of the mathematician to try to make sense of the physicists manipulations and give proper meaning to the structures. (Confusing physicists is not the job of mathematicians, however mathematicians are good at it!) In this talk we will uncover the structure of Grassmann odd fields as used in physics. For example such fields appear in quasi-classical theories of fermions and in the BV-BRST quantisation of gauge theories. To understand the structures here we need to jump into the theory of supermanifolds. However we find that supermanifolds are not quite enough! We need to deploy some tools from category theory and end up thinking in terms of functors! :-O

I will try to post my notes here at some point after the talk…

    1. Thanks, I think it went okay. I get the impression that most people understood the overall message of my talk if not all the details.

      I will link to my notes shorty for those interested.
