Tautological characteristic classes III: the Witt class for PSL(2)
Jan Dymara, Tadeusz Januszkiewicz
We explain the relation between the Witt class and the universal equicommutative class for PSL(2,K). We discuss an analogue of the Milnor-Wood inequality.
Tautological characteristic classes II: the Witt class
Jan Dymara, Tadeusz Januszkiewicz
Let be an arbitrary infinite field. The cohomology group contains the class of the universal central extension. When studying representations of fu…
Tautological characteristic classes I
Jan Dymara, Tadeusz Januszkiewicz
We discuss the formalism of tautological characteristic classes of flat bundles. Applied to it yields the Witt class of Nekovar. Applied to , the general li…
Old recurrence formulae for growth series of Coxeter groups
Jan Dymara
Several classical formulae for the growth series of a Coxeter group are proved in a new way, using the structure of the Coxeter complex, the Davis complex, or the Tits non-complex.
Boundary unitary representations - right-angled hyperbolic buildings
Uri Bader, Jan Dymara
We study the unitary boundary representation of a strongly transitive group acting on a right-angled hyperbolic building. We show its irreducibility. We do so by associating to suc…
Compactly supported cohomology of buildings
Michael Davis, Jan Dymara, Tadeusz Januszkiewicz +2
We compute the compactly supported cohomology of the standard realization of any locally finite building.
