Quiver subrepresentations and the Derksen-Weyman saturation property
Velleda Baldoni, Michèle Vergne, Michael Walter
Using Schofield's characterization of the dimension vectors of general subrepresentations of a representation of a quiver, we give a direct proof of the Derksen-Weyman saturation p…
Tensor product of holomorphic discrete series representations of U(p,q) and quivers
Velleda Baldoni, Michèle Vergne
As shown by P-E Paradan, the set of orbits contained in the sum of two holomorphic orbits in the Lie algebra of U(p,q) is determined by a set of inequalities similar to the Horn in…
Horn conditions for quiver subrepresentations and the moment map
Velleda Baldoni, Michèle Vergne, Michael Walter
We give inductive conditions that characterize the Schubert positions of subrepresentations of a general quiver representation. Our results generalize Belkale's criterion for the i…
Horn inequalities and quivers
Velleda Baldoni, Michèle Vergne, Michael Walter
Let G be a complex reductive group acting on a finite-dimensional complex vector space H. Let B be a Borel subgroup of G and let T be the associated torus. The Mumford cone is the…
Computation of Dilated Kronecker Coefficients
Velleda Baldoni, Michèle Vergne, Michael Walter
The computation of Kronecker coefficients is a challenging problem with a variety of applications. In this paper we present an approach based on methods from symplectic geometry an…
Multiplicity of compact group representations and applications to Kronecker coefficients
Velleda Baldoni, Michele Vergne
These notes are an expanded version of a talk given by the second author. Our main interest is focused on the challenging problem of computing Kronecker coefficients. We decided, a…
