The injective and projective Leavitt complexes
Huanhuan Li
For a certain finite graph E, we consider the corresponding finite dimensional algebra A with radical square zero. An explicit compact generator for the homotopy category of acycli…
-graded rings as Cuntz-Pimsner rings
Lisa Orloff Clark, James Fletcher, Roozbeh Hazrat +1
Given a -graded ring and a subring , it is natural to ask whether can be realised as the Cuntz-Pimsner ring of some -system. In this paper, we…
Homology of étale groupoids, a graded approach
Roozbeh Hazrat, Huanhuan Li
We introduce a graded homology theory for graded étale groupoids. For -graded groupoids, we establish an exact sequence relating the graded zeroth-homology to non-graded…
Simple flat Leavitt path algebras are von Neumann regular
A. A. Ambily, Roozbeh Hazrat, Huanhuan Li
For a unital ring, it is an open question whether flatness of simple modules implies all modules are flat and thus the ring is von Neumann regular. The question was raised by Ramam…
