We show that the ring of invariants in a skew monoid ring contains a so called standard Galois order. Any Galois ring contained in the standard Galois order is automatically itself a …

In this paper, we construct, investigate and, in some cases, classify several new classes of (simple) modules over the Takiff sl 2. More precisely, we first explicitly construct and …

In the present paper we study Gelfand-Tsetlin modules defined in terms of BGG differential operators. The structure of these modules is described with the aid of the Postnikov-Stanley …

For a finite-dimensional Lie algebra over with a fixed Levi decomposition, where is semisimple, we investigate-modules which decompose, as-modules, into a direct sum of …
We introduce the notion of essential support of a simple Gelfand-Tsetlin gl n-module as an attempt to understand the character formula of such module. This support detects the …

We prove that an invariant subalgebra A n W of the Weyl algebra A n is a Galois order over an adequate commutative subalgebra Γ when W is a two-parameters irreducible unitary …

We prove that applying a projective functor to a simple module over a semi-simple finite dimensional complex Lie algebra produces a module that has an essential semi-simple …
