Generic Rigidity of Graph Frameworks in Euclidean Space

Alexander Heaton

The combinatorial characterization of generic rigidity for bar-joint frameworks in dimensions $d \geq 3$ has been a long-standing open problem in discrete geometry. While the two-di…

Graded multiplicity in harmonic polynomials from the Vinberg setting

Alexander Heaton

We consider Vinberg $I^¸$ -groups associated to a cyclic quiver on $r$ nodes. Let $K$ be the product of general linear groups associated to the nodes, acting naturally on $V = \oplus…

Stable Graded Multiplicities for Harmonics on a Cyclic Quiver

Andrew Frohmader, Alexander Heaton

We consider Vinberg $I^¸$ -groups associated to a cyclic quiver on $k$ nodes. Let $K$ be the product of the general linear groups associated to each node. Then $K$ acts naturally on…
