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…

Hidden Yangian symmetry in sigma model on squashed sphere
Io Kawaguchi, Kentaroh Yoshida
We discuss a hidden symmetry of a two-dimensional sigma model on a squashed S^3. The SU(2) current can be improved so that it can be regarded as a flat connection. Then we can obta…
