Anomalous symmetries in Kähler geometry
Dmitri Bykov, Andrew Kuzovchikov
We initiate a study of centrally extended () symmetries in Kähler geometry, focusing on the simplest, and most ubiquitous, Abelian case. In particular, we provi…
Ricci-flat metrics from gauged linear -models without RG flow
Dmitri Bykov, Ondrej Hulik, Ulf Lindström +2
We investigate a class of Ricci-flat Kähler metrics on generalized conifolds constructed via gauged linear sigma models (GLSMs) with indefinite signature. By introducing shadow coo…
The Large Vector Multiplet and Gauging -models
Dmitri Bykov, Ulf Lindström, Martin RoÄek
The Large Vector Multiple (LVM) is the relevant gauge multiplet for gauging isometries acting on both the chiral and the twisted chiral fields in a sigma model. Here we sh…
Holomorphic Quantization in Constant Curvature Backgrounds
Dmitri Bykov, Viacheslav Krivorol
We present a holomorphic quantization scheme for free point particles on two-dimensional constant curvature Riemannian backgrounds. The procedure is based on a Lagrangian embedding…
