Towards bosonization of Virasoro coadjoint orbits
Anton Alekseev, Olga Chekeres, Donald R. Youmans
We show that Schwarzian theories associated to certain hyperbolic and parabolic Virasoro coadjoint orbits admit bosonization, i.e. a global -equivariant Darboux chart in which…
Renormalization group flow of Chern-Simons boundary conditions and generalized Ricci tensor
Ján Pulmann, Pavol Ševera, Donald R. Youmans
We find a Chern-Simons propagator on the ball with the chiral boundary condition. We use it to study perturbatively Chern-Simons boundary conditions related to 2-dim -models and…
Schwarzian quantum mechanics as a Drinfeld-Sokolov reduction of theory
Fridrich Valach, Donald Ray Youmans
We give an interpretation of the holographic correspondence between two-dimensional theory on the punctured disk with gauge group and Schwarzian quant…
Two-dimensional non-abelian BF theory in Lorenz gauge as a solvable logarithmic TCFT
Andrey S. Losev, Pavel Mnev, Donald R. Youmans
We study two-dimensional non-abelian BF theory in Lorenz gauge and prove that it is a topological conformal field theory. This opens the possibility to compute topological string a…
