Let $S = \mathbb{C}[x_{i,j}]$ be the ring of polynomial functions on the space of $m \times n$ matrices, and consider the action of the group $\mathbf{GL} = \mathbf{GL}_m \times \mathbf{GL}_n$ via row and column operations on the matrix entries. It is proven by Raicu and Weyman that for a $\mathbf{GL}$-invariant ideal $I \subseteq S$, the linear strands of its minimal free resolution translates via the BGG correspondence to modules over the general linear Lie superalgebra $\mathfrak{gl}(m|n… ## References SHOWING 1-10 OF 17 REFERENCES Syzygies of Determinantal Thickenings and Representations of the General Linear Lie Superalgebra • Mathematics Acta Mathematica Vietnamica • 2018 We let S=ℂ[xi,j]$S=\mathbb C[x_{i,j}]$denote the ring of polynomial functions on the space of m×n$m\times n$matrices and consider the action of the group GL=GLm×GLn$\text {GL}=\text {GL}_{m}\times

The vector space of m x n complex matrices (m >= n) admits a natural action of the group GL = GL_m x GL_n via row and column operations. For positive integers a,b, we consider the ideal I_{a x b}

A Jantzen type filtration for generalised Varma modules of Lie superalgebras is introduced. In the case of type I Lie superalgebras, it is shown that the generalised Jantzen filtration for any Kac

Highest weight categories arising from Khovanov's diagram algebra IV: the general linear supergroup
• Mathematics
• 2009
We prove that blocks of the general linear supergroup are Morita equivalent to a limiting version of Khovanov's diagram algebra. We deduce that blocks of the general linear supergroup are Koszul.
