A generalized uniqueness theorem and the graded ideal structure of Steinberg algebras

L Orloff Clark, R Exel, E Pardo - Forum Mathematicum, 2018 - degruyter.com
Given an ample, Hausdorff groupoid 𝒢, and a unital commutative ring R, we consider the
Steinberg algebra AR⁢(𝒢). First we prove a uniqueness theorem for this algebra and then …

Maximal commutative subalgebras of Leavitt path algebras

G Bajor, A Cichocka, L Wyk… - Communications in …, 2024 - World Scientific
Let K be a field, and let E be a row-finite (directed) graph. We present a construction of a
wealth of maximal commutative subalgebras of the Leavitt path algebra LK (E), which is a far …

Construction of a class of maximal commutative subalgebras of prime Leavitt path algebras

G Bajor, L van Wyk, M Ziembowski - Forum Mathematicum, 2021 - degruyter.com
Considering prime Leavitt path algebras LK⁢(E), with E being an arbitrary graph with at
least two vertices, and K being any field, we construct a class of maximal commutative …

Homomorphisms of Complex Kumjian-Pask Algebras

R Rosjanuardi, ECM Asih - Journal of the Indonesian Mathematical …, 2023 - jims-a.org
Let Λ and Γ be row finite k-graphs without sources. We show that∗-algebra homomorphisms
ϕ: KPC (Λ)→ KPC (Γ) extend to∗-algebra homomorphisms ϕ: C∗(Λ)→ C∗(Γ). We also …

A note on the centralizer of a subalgebra of the Steinberg algebra

R Hazrat, H Li - St. Petersburg Mathematical Journal, 2022 - ams.org
For an ample Hausdorff groupoid $\mathcal {G} $, and the Steinberg algebra $ A_R
(\mathcal {G}) $ with coefficients in the commutative ring $ R $ with unit, the centralizer is …

Representing k-graphs as Matrix Algebras

R Rosjanuardi - Journal of Physics: Conference Series, 2018 - iopscience.iop.org
For any commutative unital ring R and finitely aligned k-graph Λ with| Λ|<∞ without cycles,
we can realise Kumjian-Pask algebra KP R (Λ) as a direct sum of of matrix algebra over …

On the structure of Leavitt path algebras and Kumjian-Pask algebras.

C Gil-Canto - 2017 - riuma.uma.es
In the early 1960's WG Leavitt gave examples of algebras not satisfying the Invariant Basis
Number (IBN) property. It is known that a unital ring S has the Invariant Basis Number (IBN) …
