APCTP 2004-001 Geometrical Loci and CFTs via the Virasoro Symmetry of the mKdV-SG hierarchy: an excursus
نویسنده
چکیده
We will describe the appearance of specific algebraic KdV potentials as a consequence of a requirement on a integro-differential expression. This expression belongs to a class generated by means of Virasoro vector fields acting on the KdV field. The “almost” rational KdV fields are described in terms of a geometrical locus of complex points. A class of solutions of this locus has recently appeared as a description of any conformal Verma module without degeneration. PACS: 11.30-j; 02.40.-k; 03.50.-z

Hidden Virasoro Symmetry of the Sine Gordon Theory
In the framework of the Sine-Gordon (SG) theory we will present the construction of a dynamical Virasoro symmetry which has nothing to do with the space-time Virasoro symmetry of 2D CFT. Although, it is non-local in the SG field theory, nevertheless it gives rise to a local action on specific N-soliton solution variables. These analytic variables possess a beautiful geometrical meaning and ente...
متن کاملA Combined Sine-gordon and Modified Korteweg{de Vries Hierarchy and Its Algebro-geometric Solutions
We derive a zero-curvature formalism for a combined sine-Gordon (sG) and modi-ed Korteweg{de Vries (mKdV) equation which yields a local sGmKdV hierarchy. In complete analogy to other completely integrable hierarchies of soliton equations, such as the KdV, AKNS, and Toda hierarchies, the sGmKdV hierarchy is recursively constructed by means of a fundamental polynomial formalism involving a spectr...
متن کاملAspects of Symmetry in Sine-Gordon Theory
As a prototype of powerful non-abelian symmetry in an Integrable System, I will show the appearance of a Witt algebra of vector fields in the SG theory. This symmetry does not share anything with the well-known Virasoro algebra of the conformal c = 1 unperturbed limit. Although it is quasi-local in the SG field theory, nevertheless it gives rise to a local action on N -soliton solution variable...
متن کاملAsymptotic symmetries of Schrödinger spacetimes
We discuss the asymptotic symmetry algebra of the Schrödinger-invariant metrics in d + 3 dimensions and its realization on finite temperature solutions of gravity coupled to matter fields. These solutions have been proposed as gravity backgrounds dual to non-relativistic CFTs with critical exponent z in d space dimensions. It is known that the Schrödinger algebra possesses an infinite-dimension...
متن کامل, mKdV , SINE - GORDON SOLITON EQUATIONS
A bi-Hamiltonian hierarchy of complex vector soliton equations is derived from geometric flows of non-stretching curves in the Lie groups G = SO(N + 1), SU(N) ⊂ U(N), generalizing previous work on integrable curve flows in Riemannian symmetric spaces G/SO(N). The derivation uses a parallel frame and connection along the curves, involving the Klein geometry of the group G. This is shown to yield...
