Bounding the Dimensions of Rational Cohomology Groups,igate situations where the dimension of a rational cohomology group for . can be bounded by a constant times the dimension of the coefficient module. As an application, effective bounds on the first cohomology of the symmetric group are obtained. We also show how, for finite Chevalley groups, our me

Representations of the General Linear Lie Superalgebra in the BGG Category ,, the analog of the Kazhdan–Lusztig conjecture as formulated by the author in 2002, which was finally proved in 2011 by Cheng, Lam and Wang. Recently another proof has been obtained by the author joint with Losev and Webster, by a method which leads moreover to the construction of a Koszul-graded lif

Three Results on Representations of Mackey Lie Algebras,f . whose duals preserve .. In their work, the category . of .-modules, which are finite length subquotients of the tensor algebra ., is singled out and studied. Denoting by . the category with the same objects as . but regarded as . ⊗ .-modules, we first show that when . and . are paired by dual ba

Cleft Extensions and Quotients of Twisted Quantum Doubles, cleft extension . where . denotes some suitable cohomological data. When . is a quotient of . by a central subgroup . acting trivially on ., we give necessary and sufficient conditions for the existence of a surjection of quasi-Hopf algebras and cleft extensions of the type .. Our construction is p

On Exceptional Vertex Operator (Super) Algebras,the primary vectors of lowest conformal weight are Virasoro descendents of the vacuum. We show that the genus one partition function and characters for simple ordinary modules must satisfy modular linear differential equations. We show the rationality of the central charge and lowest weights of modu
