We present a proof for certain cases of the noncommutative Borsuk-Ulam conjectures proposed by Baum, Dabrowski, and Hajac. When a unital C*-algebra A admits a free action of ℤ/kℤ, k ≥ 2, there is no ...
In the representation theory of selfinjective artin algebras an important role is played by selfinjective algebras of the form $\widehat{B}/G$ where $\widehat{B}$ is the repetitive algebra of an artin ...
