Gauge Theory, Hyperbolic Geometry and Virasoro Coadjoint Orbits
Matthias Blau, Donald R. Youmans
It has long been known that the moduli space of hyperbolic metrics on the disc can be identified with the Virasoro coadjoint orbit $\mathrm{Diff}^+(S^1) / \mathrm{SL}(2,\mathbb{R})…
On enumerative problems for maps and quasimaps: freckles and scars
Olga Chekeres, Santosh Kandel, Andrey Losev +3
We address the question of counting maps between projective spaces such that images of cycles on the source intersect cycles on the target. In this paper we do it by embedding maps…
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…
Two field-theoretic viewpoints on the Fukaya-Morse category
Olga Chekeres, Andrey Losev, Pavel Mnev +1
We study an enhanced version of the Morse degeneration of Fukaya category with higher compositions given by counts of gradient flow trees. The enhancement consists in al…
Theory of holomorphic maps of two-dimensional complex manifolds to toric manifolds and type A multi-string theory
Olga Chekeres, Andrey S. Losev, Pavel Mnev +1
We study the field theory localizing to holomorphic maps from a complex manifold of complex dimension 2 to a toric target (a generalization of A model). Fields are realized as maps…
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…
Two-dimensional abelian BF theory in Lorenz gauge as a twisted N=(2,2) superconformal field theory
Andrey S. Losev, Pavel Mnev, Donald R. Youmans
We study the two-dimensional topological abelian BF theory in the Lorenz gauge and, surprisingly, we find that the gauged-fixed theory is a free type B twisted N=(2,2) superconform…
The double scaling limit of the multi-orientable tensor model
Razvan Gurau, Adrian Tanasa, Donald R. Youmans
In this paper we study the double scaling limit of the multi-orientable tensor model. We prove that, contrary to the case of matrix models but similarly to the case of invariant te…
