An asymptotic homotopy lifting property

José R. Carrión, Christopher Schafhauser

A -algebra is said to have the homotopy lifting property if for all -algebras and , for every surjective -homomorphism and for ev…

Tracially Complete C*-Algebras

José R. Carrión, Jorge Castillejos, Samuel Evington +4

We introduce a new class of operator algebras -- tracially complete C*-algebras -- as a vehicle for transferring ideas and results between C*-algebras and their tracial von Neumann…

Nuclear dimension of graph C-algebras with Condition~(K)

Gregory Faurot, Christopher Schafhauser

We prove that for any countable directed graph with Condition~(K), the associated graph -algebra has nuclear dimension at most . Furthermore, we provide a suff…

Classifying -homomorphisms I: Unital simple nuclear -algebras

José R. Carrión, James Gabe, Christopher Schafhauser +2

We classify the unital embeddings of a unital separable nuclear -algebra satisfying the universal coefficient theorem into a unital simple separable nuclear -algebra that…

A topology on E-theory

José R. Carrión, Christopher Schafhauser

For separable -algebras and , we define a topology on the set consisting of homotopy classes of asymptotic morphisms from to . This gives an enrichmen…

Finite dimensional approximations of certain amalgamated free products of groups

Christopher Schafhauser

A group is called matricial field (MF) if it admits finite dimensional approximate unitary representations which are approximately faithful and approximately contained in the left…
