Poisson reductions of master integrable systems on doubles of compact Lie groups
L. Feher
We consider three 'classical doubles' of any semisimple, connected and simply connected compact Lie group : the cotangent bundle, the Heisenberg double and the internally fused…
Characteristic classes of orbit stratifications, the axiomatic approach
Laszlo M. Feher, Richard Rimanyi, Andrzej Weber
Consider a complex algebraic group acting on a smooth variety with finitely many orbits, and let be an orbit. The following three invariants of can be char…
Motivic Chern classes and K-theoretic stable envelopes
Laszlo M. Feher, Richard Rimanyi, Andrzej Weber
We study a K-theoretic characteristic class of singular varieties, namely the equivariant motivic Chern class. We prove that the motivic Chern class is characterized by an axiom sy…
Chern-Schwartz-MacPherson classes of degeneracy loci
L. M. Feher, R. Rimanyi
The Chern-Schwartz-MacPherson class (CSM) and the Segre-Schwartz-MacPherson class (SSM) are deformations of the fundamental class of an algebraic variety. They encode finer enumera…
Real solutions of a problem in enumerative geometry
László M. Fehér, Ákos K. Matszangosz
We study a 2-parameter family of enumerative problems over the reals. Over the complex field, these problems can be solved by Schubert calculus. In the real case the number of solu…
Equivariant and invariant theory of nets of conics
M. Domokos, L. M. Feher, R. Rimanyi
Two parameter families of plane conics are called nets of conics. There is a natural group action on the vector space of nets of conics, namely the product of the group reparametri…
