In this paper, we study weight representations over the Schrodinger Lie algebra s n for any positive integer n. It turns out that the algebra s n can be realized by polynomial differential operators. Using this realization, we give a complete classif

The rank n symplectic oscillator Lie algebra 𝔤n is the semidirect product of the symplectic Lie algebra 𝔰𝔭2n and the Heisenberg algebra Hn. In this paper, we first study weight modules with finite-dimensional weight spaces over 𝔤n. When t

For a commutative algebra A over C, denote g=Der(A). A module over the smash product A#U(g) is called a jet g-module, where U(g) is the universal enveloping algebra of g. In the present paper, we s...

In this paper, we study the BGG category $\mathcal{O}$ for the quantum Schr{\"o}dinger algebra $U_q(\mathfrak{s})$, where $q$ is a nonzero complex number which is not a root of unity. If the central charge $\dot z\neq 0$, using the module $B_{\dot z}

Let $d\ge1$ be an integer, $W_d$ and $\mathcal{K}_d$ be the Witt algebra and the weyl algebra over the Laurent polynomial algebra $A_d=\mathbb{C} [x_1^{\pm1}, x_2^{\pm1}, ..., x_d^{\pm1}]$, respectively. For any $\mathfrak{gl}_d$-module $M$ and any a

For an irreducible module P over the Weyl algebra K n + (resp. K n ) and an irreducible module M over the general linear Lie algebra gl n , using Shen's monomorphism, we make P ⊗ M into a module over the Witt algebra W n + (resp. over W n ). We obt

In 2006, Gao and Zeng (Gao and Zeng, 2006) gave the free field realizations of highest weight modules over the extended affine Lie algebras g l 2 ( C q ) for any nonzero q ∈ C . In the present paper, applying the technique of localization to those

A class of generalized Verma modules over sl n + 2 are constructed from sl n + 1 -modules which are U ( h n ) -free modules of rank 1. The necessary and sufficient conditions for these sl n + 2 -modules to be simple are determined. This leads to a cl

Let n > 1 be an integer, α ∈ C n , b ∈ C , and V a gl n -module. We define a class of weight modules F b α ( V ) over sl n + 1 using the restriction of modules of tensor fields over the Lie algebra of vector fields on n-dimensional torus. In th
