Free field realizations of the elliptic affine Lie algebra sl(2, R) circle plus (Omega(R)/dR)
(ELSEVIER SCIENCE BV, 2009)
In this paper we construct two free field realizations of the elliptic affine Lie algebra sl(2, R) circle plus Omega(R)/dR where R = C[t. t(-1), u vertical bar u(2) = t(3) - 2bt(2) + t]. The first realization provides an ...
Renormalization for piecewise smooth homeomorphisms on the circle
(Annales de l'Institut Henri Poincaré (C) Non Linear AnalysisBrasil, 2013)
In this work we study the renormalization operator acting on piecewise smooth homeomorphisms on the circle, that turns out to be essentially the study of Rauzy–Veech renormalizations of generalized interval exchange maps ...

Vertex operators and soliton solutions of affine Toda model with U(2) symmetry
(Iop Publishing Ltd, 2004-06-18)
The symmetry structure of the non-Abelian affine Toda model based on the coset SL(3)/SL(2) circle times U(1) is studied. It is shown that the model possess non-Abelian Noether symmetry closing into a q-deformed SL(2) circle ...

A new deformation of W-infinity and applications to the two-loop WZNW and conformal affine Toda models
(Elsevier B.V., 1992-12-01)
We construct a centerless W-infinity type of algebra in terms of a generator of a centerless Virasoro algebra and an abelian spin 1 current. This algebra conventionally emerges in the study of pseudo-differential operators ...
Super-WZNW with reductions to supersymmetric and fermionic integrable models
(Elsevier B.V., 2009-11-11)
A systematic construction for an action describing a class of supersymmetric integrable models as well as for pure fermionic theories is discussed in terms of the gauged WZNW model associated to half integer graded affine ...
