摘　　要：We study the convolution algebra H_(*)^(G×C^(*))(Z)of G×C^(*)-equivariant homology group on the Steinberg variety of type B/C and define an algebra Y that maps to H_(*)^(G×C^(*))(Z).We also study the G-equivariant case and prove that there is a map from a certain twisted current algebra to H_(*)^(G)(Z).
