Ganea decompositions of classifying spaces

Yuri Berest, Yun Liu, Ajay C. Ramadoss

We study homotopy decompositions of the classifying spaces of compact connected Lie groups obtained by (relative) fiber-cofiber construction. Given a pair of Borel fibrations…

Quasi-flag manifolds and moment graphs

Yuri Berest, Yun Liu, Ajay C. Ramadoss

We introduce and study a new class of topological -spaces generalizing the classical flag manifolds of compact connected Lie groups. These spaces, which we call the -qu…

Topological realization of algebras of quasi-invariants, I (with an Appendix by M. V. Feigin and K. E. Feldman)

Yuri Berest, Ajay C. Ramadoss

This is the first in a series of papers, where we introduce and study topological spaces that realize the algebras of quasi-invariants of finite reflection groups. Our result can b…

Symmetric Homology is Representation Homology

Yuri Berest, Ajay C. Ramadoss

Symmetric homology is a natural generalization of cyclic homology, in which symmetric groups play the role of cyclic groups. In the case of associative algebras, the symmetric homo…

Derived Character Maps of Groups Representations

Yuri Berest, Ajay C. Ramadoss

In this paper, we construct and study derived character maps of finite-dimensional representations of -groups. As models for -groups we take homotopy simplicial gro…

Representation homology of simply connected spaces

Yuri Berest, Ajay C. Ramadoss, Wai-Kit Yeung

Let be an affine algebraic group defined over field of characteristic zero. We study the derived moduli space of G-local systems on a pointed connected CW complex X trivial…
