【摘要】 We have studied Yang-Baxter deformations of supercoset sigma models with Z_4m grading.The deformations are specified by a skew-symmetric classical r-matrix satisfying the classical Yang-Baxter equations.The deformed action is constructed and the Lax pair is also presented.When m= 1,our results reduce to those of the type ⅡB Green-Schwarz superstring on AdS₅×S⁵ background recently given by Kawaguchi,Matsumoto and Yoshida.更多还原
