As a result, an identification between the second homology group of the Lie superalgebra ospm|2n (R,-) and the first skew-dihedral homology group of the associative superalgebra (R,-) with superin-volution is created for positive integers m and n with (m, n)≠ (1, 1) and (m, n)≠(2, 1).

文摘We completely determine the universal central extension of the generalized orthosymplectic Lie superalgebra ospm 12n(R,-) that is coordinatized by an arbitrary unital associative superalgebra (R,-) with superinvolution.
