Hybrid classical integrable structure of squashed sigma models -- a short summary
Io Kawaguchi, Kentaroh Yoshida
We give a short summary of our recent works on the classical integrable structure of two-dimensional non-linear sigma models defined on squashed three-dimensional spheres. There ar…
Classical integrability of Schrodinger sigma models and q-deformed Poincare symmetry
Io Kawaguchi, Kentaroh Yoshida
We discuss classical integrable structure of two-dimensional sigma models which have three-dimensional Schrodinger spacetimes as target spaces. The Schrodinger spacetimes are regar…
Hybrid classical integrability in squashed sigma models
Io Kawaguchi, Kentaroh Yoshida
We show that SU(2)_L Yangian and q-deformed SU(2)_R symmetries are realized in a two-dimensional sigma model defined on a three-dimensional squashed sphere. These symmetries enable…
Yangian symmetry in deformed WZNW models on squashed spheres
Io Kawaguchi, Domenico Orlando, Kentaroh Yoshida
We introduce a deformation of the Wess-Zumino-Novikov-Witten model with three-dimensional squashed sphere target space. We show how with an appropriate choice of Wess--Zumino and b…
