On the Cohomological Hall Algebra of Dynkin quivers
R. Rimanyi
Consider the Cohomological Hall Algebra as defined by Kontsevich and Soibelman, associated with a Dynkin quiver. We reinterpret the geometry behind the multiplication map in the CO…

Quiver polynomials in iterated residue form
Richard Rimanyi
Degeneracy loci polynomials for quiver representations generalize several important polynomials in algebraic combinatorics. In this paper we give a nonconventional generating seque…

Partial flag varieties, stable envelopes and weight functions
R. Rimanyi, V. Tarasov, A. Varchenko
We consider the cotangent bundle T^*F_λof a GL_n partial flag variety, λ= (λ_1,...,λ_N), |λ|=\sum_iλ_i=n, and the torus T=(C^*)^{n+1} equivariant cohomology H^*_T(T^*F_λ). In [MO],…
