Geometric invariants of locally compact groups: the homological perspective
Kai-Uwe Bux, Elisa Hartmann, José Pedro Quintanilha
In this paper we develop the homological version of -theory for locally compact Hausdorff groups, leaving the homotopical version for another paper. Both versions are connected…

Geometric invariants of locally compact groups: the homotopical perspective
Kai-Uwe Bux, Elisa Hartmann, José Pedro Quintanilha
We extend the classical theory of homotopical -sets developed by Bieri, Neumann, Renz and Strebel for abstract groups, to -sets for locally com…

Computer-assisted methods in Sigma-theory
Elisa Hartmann
We develop an algorithm for recognizing whether a character belongs to . In order to apply it we just need to know that the ambient group is of type or of typ…
