Northern California Symplectic Geometry Seminar: Dilogarithms and abelian Chern-Simons
Seminar | February 3 | 4-5 p.m. | 891 Evans Hall
Dan Freed, UT Austin
In joint work with Andy Neitzke we discovered a construction of the dilogarithm function from the Chern-Simons function for the group C*. This leads, for example, to a geometric derivation of dilogarithm identities. In the talk I will review the geometry of the Chern-Simons function, including the variation for spin manifolds needed in this application.
