Poincare-Birkhoff-Witt expansions of the canonical elliptic differential form

G. Felder, R. Rimanyi, A. Varchenko

We study the canonical U(\n)-valued elliptic differential form, whose projections to different Kac-Moody algebras are key ingredients of the hypergeometric integral solutions of el…

A formula for non-equioriented quiver orbits of type A

A. S. Buch, R. Rimanyi

We prove a positive combinatorial formula for the equivariant class of an orbit closure in the space of representations of an arbitrary quiver of type . Our formula expresses th…

Combinatorics of rational functions and Poincare-Birkhoff-Witt expansions of the canonical U(n-)-valued differential form

R. Rimanyi, L. Stevens, A. Varchenko

We study the canonical U(n-)-valued differential form, whose projections to different Kac-Moody algebras are key ingredients of the hypergeometric integral solutions of KZ-type dif…

Coincident root loci of binary forms

L. M. Feher, A. Nemethi, R. Rimanyi

Coincident root loci are subvarieties of --the space of binary forms of degree --labelled by partitions of . Given a partition , let be the set of forms wi…

Positivity of quiver coefficients through Thom polynomials

A. S. Buch, L. M. Feher, R. Rimanyi

Let r be an orbit of the quiver representation of type A_n (equioriented case). In this paper we study the Poincare dual of the closure of r (a.c.a. Thom polynomial/degeneracy loci…

Specializations of Grothendieck polynomials

Anders S. Buch, Richard Rimanyi

We prove a formula for double Schubert and Grothendieck polynomials specialized to two rearrangements of the same set of variables. Our formula generalizes the usual formulas for S…
