Higher-rank graphs and the graded -theory of Kumjian-Pask algebras

Roozbeh Hazrat, Promit Mukherjee, David Pask +1

This paper lays out the foundations of graded -theory for Leavitt algebras associated with higher-rank graphs, also known as Kumjian-Pask algebras, establishing it as a potentia…

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…

Graded Steinberg algebras and their representations

Pere Ara, Roozbeh Hazrat, Huanhuan Li +1

We study the category of left unital graded modules over the Steinberg algebra of a graded ample Hausdorff groupoid. In the first part of the paper, we show that this category is i…

Homogeneous SK1 of simple graded algebras

R. Hazrat, A. R. Wadsworth

For a simple graded algebra A=M_n(E) over a graded division algebra E, a short exact sequence relating the reduced Whitehead group of the homogeneous part of A to that of E is esta…

On Quillen's calculation of graded -theory

R. Hazrat, T. Huettemann

We adapt Quillen's calculation of graded K-groups of Z-graded rings with support in N to graded K-theory, allowing gradings in a product Z \times G with G an arbitrary group. This…

On Graded Simple Algebras

R. Hazrat, J. Millar

This note begins by observing that a graded central simple algebra, graded by an abelian group, is a graded Azumaya algebra and it is free over its centre. For a graded Azumaya alg…
