چکیده

Abstract In this section, we study representation theory of DAHA, strictly speaking, the spherical subalgebra DAHA type $$A_1$$ A 1 , in terms brane quantization 2d A -model [85] on moduli space flat $${{\,\textrm{SL}\,}}(2,\mathbb {C})$$ SL ( 2 , C ) -connections a once-punctured torus. The lends itself well to geometric approach which provides novel viewpoints.

Graded Poisson-Sigma Models and Dilaton-Deformed 2D Supergravity Algebra

Fermionic extensions of generic 2d gravity theories obtained from the graded Poisson-Sigma model (gPSM) approach show a large degree of ambiguity. In addition, obstructions may reduce the allowed range of fields as given by the bosonic theory, or even prohibit any extension in certain cases. In our present work we relate the finite W-algebras inherent in the gPSM algebra of constraints to algeb...

Light-Cone Gauge Quantization of 2D Sigma Models

This work describes the formulation of the manifestly ghost-free (spacetime) light-cone gauge for bosonic string theory with non-trivial spacetime metric, antisymmetric tensor, dilaton and tachyon fields. The action is a general two-dimensional sigma model, corresponding to a closed string theory with a second order action in the Polyakov picture. The spacetime fields must have a symmetry gener...

Central Charge Anomalies in 2D Sigma Models with Twisted Mass

We discuss the central charge in supersymmetric N = 2 sigma models in two dimensions. The target space is a symmetric Kähler manifold; CP(N−1) is an example. The U(1) isometries allow one to introduce twisted masses in the model. At the classical level the central charge contains Noether charges of the U(1) isometries and a topological charge which is an integral of a total derivative of the Ki...

Supermagnets and Sigma models

We discuss new methods for non-compact sigma models with and without RR fluxes.The methods include reduction to one dimensional supermagnets,supercoset constructions and supertwistors.This work is a first step towards the solution of these models,which are important in several areas of physics. I dedicate it to the memory of Volodya Gribov.

The Complete Solution of 2d Superfield Supergravity from Graded Poisson-sigma Models and the Super Pointparticle

Recently an alternative description of 2d supergravities in terms of graded Poisson-Sigma models (gPSM) has been given. As pointed out previously by the present authors a certain subset of gPSMs can be interpreted as “genuine” supergravity, fulfilling the well-known limits of supergravity, albeit deformed by the dilaton field. In our present paper we show that precisely that class of gPSMs corr...
