Yangians of the “strange” lie superalgebras
Consider the matrix Lie superalgebra A=gℓ(n|n, ℂ) with the standard generators e ij ; i, j ε ℤ2n. Define an automorphism π of A by π(e ij )=ei+n,j+n. The automorphisms π and −π o t, where t denotes the amtrix supertransposition, are involutory. Dissimilarly to the even case, Open image in new window is constructed. It gives rise to new solutions of the Yang-Baxter equation.
