Speaker: Jonathan Rosenberg, William Linch, Richard Wentworth (UMCP) -

Abstract: We'll give a quick non-technical introduction to a number of possible topics linking geometry and physics, and then try to decide how to proceed.

Speaker: William Linch (UMCP) -

Abstract: We will start going over the basic prerequisites for the planned main topics of discussion, and show how sigma models cover many basic ideas in physics and differential geometry.

But you might want to attend the physics colloquium by Charles Doran on 2/18, which is about the mathematics of supersymmetry.

Speaker: William Linch (UMCP)

Abstract: We'll continue the discussion of sigma models and variational problems to see how they encode things like gauge fields. If time permits, we might move on to basics of supersymmetry.

Abstract: We give a mathematician's approach to supermanifolds and superfields.

Speaker: Paul Green (UMCP)

Abstract: A spin structure, or spinor bundle, on a circle or Riemann surface is a square root of the one(respectively real or complex)-dimensional tangent bundle. By interpreting the Jacobi identities for a super-Lie algebra in a conceptual way , which makes it unnecessary to worry about signs, we are able to assign, in a unique way, an infinite dimensional super-Lie algebra structure to every circle or Riemann surface with spin structure, where the even part consists of smooth (respectively, meromorphic) vector fields, and the odd part consists of sections of the spinor bundle. All of this plays an important role in analyzing the concept of a conformal field theory in the sense of Segal.
