Denominator identity for affine Lie superalgebras with zero dual Coxeter number
Denominator identity affine Lie superalgebras zero dual Coxeter number
2011/2/28
We prove a denominator identity for non-twisted affine Lie superalgebras with zero dual Coxeter number.
Finite $W$-superalgebras for queer Lie superalgebras and higher Sergeev duality
Finite $W$-superalgebras queer Lie superalgebras higher Sergeev duality
2011/1/20
We initiate and develop the theory of finite W-superalgebras W associated to the queer Lie superalgebra g = q(N) and a nilpotent linear func-tional ∈ g ¯0 . We show that the definition of th...
On cohomology and support varieties for Lie superalgebras
cohomology varieties Lie superalgebras
2010/12/8
Support varieties for Lie superalgebras over the complex numbers were introduced in [BKN1] using the relative cohomology. In this paper we discuss finite generation of the relative cohomology rings fo...
Yang-Baxter operators from algebra structures and Lie superalgebras
Yang-Baxter operators algebra structures Lie superalgebras
2010/11/29
We present solutions for the (constant and spectral-parameter) Yang-Baxter equations and Yang-Baxter systems arising from algebra struc-tures. In the last section, we present enhanced versions of Theo...
