Largest ideals in Leavitt path algebras.
(Springer Nature, 2020-02-22)We identify largest ideals in Leavitt path algebras: the largest locally left/right artinian (which is the largest semisimple one), the largest locally left/right noetherian without minimal idempotents, the largest exchange, ... -
Leavitt path algebras of Cayley graphs C_n^j.
(Springer Nature, 2018-09-15)Let n be a positive integer. For each 0 <= j <= n-1 we let C_n^j denote the Cayley graph of the cyclic group Zn with respect to the subset {1,j}. Utilizing the Smith Normal Form process, we give an explicit description of ... -
Quasi-closed elements in fuzzy posets
(ELSEVIER, 2022-04)We generalize the notion of quasi-closed element to fuzzy posets in two stages: First, in the crisp style in which each element in a given universe either is quasi-closed or not. Second, in the graded style by defining ... -
Representations of relative Cohn path algebras.
(Elsevier, 2020-01-07)We study relative Cohn path algebras, also known as Leavitt-Cohn path algebras, and we realize them as partial skew group rings. To do this we prove uniqueness theorems for relative Cohn path algebras. Furthermore, given ... -
The cycline subalgebra of a Kumjian-Pask algebra.
(American Mathematical Society, 2016-11-21)Let $\Lambda$ be a row-finite higher-rank graph with no sources. We identify a maximal commutative subalgebra $\mathcal{M}$ inside the Kumjian-Pask algebra ${\rm KP}_R(\Lambda)$. We also prove a generalized Cuntz-Krieger ...
