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… 


Syzygies of Determinantal Thickenings and Representations of the General Linear Lie Superalgebra
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
Kazhdan-Lusztig polynomials and character formulae for the Lie superalgebra gl(m|n)
The problem of computing the characters of the finite dimensional irreducible representations of the Lie superalgebra $\mathfrak{gl}(m|n)$ over $\C$ was solved a few years ago by V. Serganova. In
The syzygies of some thickenings of determinantal varieties
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}
Highest weight categories arising from Khovanov's diagram algebra III: category O
We prove that integral blocks of parabolic category O associated to the subalgebra gl(m) x gl(n) of gl(m+n) are Morita equivalent to quasi-hereditary covers of generalised Khovanov algebras. Although
Dualities and Representations of Lie Superalgebras
This book gives a systematic account of the structure and representation theory of finite-dimensional complex Lie superalgebras of classical type and serves as a good introduction to representation
Generalised Jantzen filtration of Lie superalgebras I
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
