q - Virasoro Algebra and the Point - Splitting
It is shown that a particular q-deformation of the Virasoro algebra can be interpreted in terms of the q-local field Φ(x) and the Schwinger-like point-splitted Virasoro currents, quadratic in Φ(x). The q-deformed Virasoro algebra possesses an additional index α, which is directly related to point-splitting of the currents. The generators in the q-deformed case are found to exactly reproduce the...
متن کاملDILOGARITHM IDENTITIES, q-DIFFERENCE EQUATIONS AND THE VIRASORO ALGEBRA
and δj = sin ( π 2n+1 )/ sin(π j+1 2n+1 ). This equality was proved by Richmond and Szekeres from the asymptotic analysis of the Gordon identities [1] and also by Kirillov using analytic methods [2]. There is a wide class of identities of this type, which emerged in recent works on two-dimensional quantum field theories and statistical mechanics. They appear in the calculation of the critical b...
متن کاملThe (Q, q)–Schur Algebra
In this paper we use the Hecke algebra of type B to define a new algebra S which is an analogue of the q–Schur algebra. We construct Weyl modules for S and obtain, as factor modules, a family of irreducible S–modules over any field.
متن کاملq-Conformal Invariant Equations and q-Plane Wave Solutions
We give new solutions of the quantum conformal deformations of the full Maxwell equations in terms of deformations of the plane wave. We study the compatibility of these solutions with the conservation of the current. We also start the study of quantum linear conformal (Weyl) gravity by writing the corresponding q-deformed equations.
متن کاملRemarks on Q-virasoro and Qkdv
In recent publications [7, 9, 11] we have explored derivations of various qKdV type and noncommutative KdV (NCKdV) equations from several points of view (e.g. differential calculi, quantum groups, hierarchies, Moyal products, Maurer-Cartan equations, zero curvature, etc.). Motivated in part by [27, 28, 29] we exhibit here a derivation from q-Virasoro ideas (see e.g. [6, 13, 16, 17, 22, 24, 25, ...
