We will extend the Hochschild-Serre spectral sequence for cohomology of Lie algebras a step further. Also, some inequalities and upper bounds for the dimension of the second cohomology of finite ...

Suppose a finite group acts on a scheme X and a finite-dimensional Lie algebra g. The corresponding equivariant map algebra is the Lie algebra M of equivariant regular maps from X to g. We classify ...

Partition theory, a central branch of combinatorial number theory, concerns itself with the enumeration and properties of the ways in which integers may be decomposed into sums of positive integers ...
