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…
Residues formulas for the push-forward in K-theory, the case of G2/P
Andrzej Weber, Magdalena Zielenkiewicz
We study residue formulas for push-forward in K-theory of homogeneous spaces. First we review formulas for classical groups, which we derive from a formula for the classical Grassm…
On the Pelczynski conjecture on Auerbach Bases
Andrzej Weber, Michał Wojciechowski
We consider Auerbach bases in Banach spaces of dimension n>2. We show that there exists at least (n-1)n/2+1 such bases. This estimate follows from the calculation of the Lusternik-…
Paths of the directed suspension
Andrzej Weber, Krzysztof Ziemiański
We prove that the loop space of the directed suspension of a directed space is homotopy equivalent to the James construction. In particular, it does not depend on the directed stru…
On rigidity of flag varieties
Andrzej Weber, Jarosław A. Wiśniewski
We prove that the variety of complete flags for any semisimple algebraic group is rigid in any smooth family of Fano manifolds.
