  THE GAUGE-INVARIANT UNIQUENESS THEOREMFOR RELATIVE CUNTZ-PIMSNER ALGEBRAS

  We present a new proof of the gauge-invariant uniqueness theorem for C*-correspondences that is conceptual and simplifies earlier arguments. The proof is based on a reasoning due to Evgenios Kakariadis, and treats all relative Cuntz-Pimsner algebras on equal f...

  THE BORSUK-ULAM THEOREM FOR LOCALLY TRIVIAL COMPACT G-SPACES

  The Borsuk-Ulam-type conjecture of Baum, Dąbrowski, and Hajac states that, given a free action of a non-trivial compact Hausdorff group G on a compact Hausdorff space X, there is no continuous G-equivariant map from the join X*G to X. The ...

  ANALYTIC CYCLIC HOMOLOGY IN POSITIVE CHARACTERISTIC

  We define a homology theory for complete torsion-free bornological algebras over a complete discrete valuation ring. The theory satisfies homotopy invariance, Morita invariance and excision. We use these properties to compute our theory for Leavitt path algebras. For coordinate rings ...

  COAMENABILITY OF TYPE-I LOCALLY COMPACT QUANTUM GROUPS VIA CONVOLUTION OPERATORS

  We say that a locally compact quantum group is type I if its universal C*-algebra (which is the universal version of the C*-algebra of continuous functions vanishing at infinity on the dual quantum group) is type I. This class of quantum&nb...
