Equivariant spaces of matrices of constant corank one
Ada Boralevi, Daniele Faenzi, Dragoş Frăţilă
We study spaces of matrices coming from irreducible representations of reductive groups over an algebraically closed field of characteristic zero and we completely classify those o…

Quadric surfaces in the Pfaffian hypersurface in
Ada Boralevi, Maria Lucia Fania, Emilia Mezzetti
We study smooth quadric surfaces in the Pfaffian hypersurface in parameterising skew-symmetric matrices of rank at most 4, not intersecting the Grass…

A construction of equivariant bundles on the space of symmetric forms
Ada Boralevi, Daniele Faenzi, Paolo Lella
We construct stable vector bundles on the space of symmetric forms of degree d in n+1 variables which are equivariant for the action of SL_{n+1}(C), and admit an equivariant free r…
