Abstract：

We study the convolution algebra H_*^G^x^G*(Z) of G-equivarianthomology group on the Steinbergvariety of type B/C and define an algebra Y that m apsto H_*^G^x^G*(Z). The Drinfeld new realization of the twisted Yangian associated to symmetric pairsis a quotient of Y. We also study the G-equivriant case and prove that the twisted Yangian is the deformation of the twisted current algebra.
