DESCRIPTION:In this talk we will explore integrable deformations of the Gx
 G/G_0 supercoset sigma model that plays a role in the Green-Schwarz formul
 ation of superstrings on AdS3 x S3 x T4 (G = PSU(1\,1|2)) and AdS3 x S3 x 
 S3 x S1 (G = D(2\,1\;α)). After reviewing the single parameter deformatio
 n of Delduc\, Magro and Vicedo\, which treats the two copies of G symmetri
 cally\, the main focus of the talk will be the construction of an asymmetr
 ic two-parameter deformation based on Κlimčík's bi-Yang-Baxter sigma mo
 del. Some evidence will also be presented for the existence of a three-par
 ameter deformation. Various interesting limits (including the squashed thr
 ee-sphere\, the Pohlmeyer-reduced theory and the mirror model) of the corr
 esponding deformed metrics will be analyzed and the issue of whether these
  models describe deformations of superstrings will be briefly discussed.\n
