Bernstein-Gelfand-Gelfand meets geometric complexity theory: resolving the 2 x 2 permanents of a 2 x n matrix

Fulvio Gesmundo, Hang, Huang +2

We describe the minimal free resolution of the ideal of $2 \times 2$ subpermanents of a $2 \times n$ generic matrix $M$ . In contrast to the case of $2 \times 2$ determinants, the $…

Top-stable degenerations of finite dimensional representations II

H. Derksen, B. Huisgen-Zimmermann, J. Weyman

Let $Λ$ be a finite dimensional algebra over an algebraically closed field. We exhibit slices of the representation theory of $Λ$ that are always classifiable in stringent geometri…
