ENLARGEABILITY AND INDEX THEORY B. Hanke and T. Schick Abstract Let M be a closed enlargeable spin manifold. We show nontriviality of the universal index obstruction in the K-theory of the maximal C ∗ -algebra of the f

THE STABLE FREE RANK OF SYMMETRY OF PRODUCTS OF SPHERES BERNHARD HANKE A BSTRACT. A well known conjecture in the theory of transformation groups states that if p is a prime and (Z/p)r acts freely on a product of k sphere

LARGE AND SMALL GROUP HOMOLOGY MICHAEL BRUNNBAUER AND BERNHARD HANKE A BSTRACT. For several instances of metric largeness like enlargeability or having hyperspherical universal covers, we construct non-large vector subsp

Poset models of topological spaces Dongsheng Zhao Abstract. We consider poset models of topological spaces and show that every T1 -space has an bounded complete algebraic poset model, thus give a positive answer to a que
