Simple restricted modules over the Heisenberg-Virasoro algebra as VOA modules

Haijun Tan, Yufeng Yao, Kaiming Zhao

In this paper, we determine all simple restricted modules over the mirror Heisenberg-Virasoro algebra , and the twisted Heisenberg-Virasoro algebra $\bar\mathfrak{D…

A new class of irreducible modules over the affine-Virasoro algebra of type

Qiu-Fan Chen, Yu-Feng Yao

In this paper, we construct a class of non-weight modules over the affine-Virasoro algebra of type by taking tensor products of a finite number of irreducible modules $M(λ, α…

On enhanced reductive groups (II): Finiteness of nilpotent orbits under enhanced group action and their closures

Bin Shu, Yunpeng Xue, Yufeng Yao

This is a sequel to \cite{osy} and \cite{sxy}. Associated with $G:=\GL_n$ and its rational representation over an algebraically closed filed $\bk$, we define an enhanced a…

Irreducible tensor product modules over the affine-Virasoro algebra of type

Qiu-Fan Chen, Yu-Feng Yao

In this paper, we construct a class of non-weight modules over the affine-Virasoro algebra of type by taking tensor products of irreducibles defined in [Q. Chen, J. Han, Non-…
