Magnons, their Solitonic Avatars and the Pohlmeyer Reduction
Timothy J. Hollowood, J. Luis Miramontes
We study the solitons of the symmetric space sine-Gordon theories that arise once the Pohlmeyer reduction has been imposed on a sigma model with the symmetric space as target. Unde…
T-duality in Massive Integrable Field Theories: The Homogeneous and Complex sine-Gordon Models
J. Luis Miramontes
The T-duality symmetries of a family of two-dimensional massive integrable field theories defined in terms of asymmetric gauged Wess-Zumino-Novikov-Witten actions modified by a pot…
Deformed W-algebras as Symmetries of Generalized Integrable Hierarchies
C. R. Fernández-Pousa, M. V. Gallas, J. L. Miramontes +1
A unified description of the relationship between the Hamiltonian structure of a large class of integrable hierarchies of equations and W-algebras is discussed. The main result is…
Integrable Systems and W-Algebras
C. R. Fernández-Pousa, M. V. Gallas, J. L. Miramontes +1
The basic concepts underlying our analysis of {\it W-algebras} as extended symmetries of integrable systems are summarized. The construction starts from the second hamiltonian stru…
