The general quadruple point formula
R. Marangell, R. Rimanyi
Maps between manifolds () have multiple points, and more generally, multisingularities. The closure of the set of points where the map has a particular…
On the structure of Thom polynomials of singularities
L. M. Feher, R. Rimanyi
Thom polynomials of singularities express the cohomology classes dual to singularity submanifolds. A stabilization property of Thom polynomials is known classically, namely that tr…
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…
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…
