A note on Chern-Weil classes of Cartan connections

open access: yes
We present a construction of Chern-Weil characteristic classes for pairs Cartan geometries sharing the same underlying data. Given any model Cartan geometry $(Q,ω)$ with underlying data $(G,V)$ and a second Cartan geometry $(P,θ)$ with the same underlying data, we define a subalgebra of polynomials on the Atiyah algebroid of $Q$ together with a ...

On the connection between Wess-Zumino-Witten and Chern-Simons theories

open access: yesPhysics Letters B, 1991
Abstract We analyze the connection between the Wess-Zumino-Witten and Chern-Simons theories from a novel viewpoint: stochastic quantization. We start from a Wess-Zumino-Witten theory in two dimensions and show that its stochastic partition function equals the BRST partition function for the Chern-Simons theory in three dimensions through an adequate ...
