Strongly graded groupoids and strongly graded Steinberg algebras
Lisa Orloff Clark, Roozbeh Hazrat, Simon W. Rigby
We study strongly graded groupoids, which are topological groupoids equipped with a continuous, surjective functor , to a discrete group , such…
Graded Steinberg algebras and partial actions
Roozbeh Hazrat, Huanhuan Li
Given a graded ample Hausdorff groupoid, we realise its graded Steinberg algebra as a partial skew inverse semigroup ring. We use this to show that for a partial action of a discre…
A note on multiplicative commutators of division rings
Roozbeh Hazrat
We give an example of a division ring whose multiplicative commutator subgroup does not generate as a vector space over its centre, thus disproving the conjecture posed in…
Leavitt path algebras: Graded direct-finiteness and graded -injective simple modules
Roozbeh Hazrat, Kulumani M. Rangaswamy, Ashish K. Srivastava
In this paper, we give a complete characterization of Leavitt path algebras which are graded - rings, that is, rings over which a direct sum of arbitrary copies of any graded…
