Congruence-simplicity of Steinberg algebras of non-Hausdorff ample groupoids over semifields
Tran Giang Nam, Jens Zumbrägel
We investigate the algebra of an ample groupoid, introduced by Steinberg, over a semifield S. In particular, we obtain a complete characterization of congruence-simpleness for Stei…

Simpleness of Leavitt Path Algebras with Coefficients in a Commutative Semiring
Yefim Katsov, Tran Giang Nam, Jens Zumbrägel
In this paper, we study ideal- and congruence-simpleness for the Leavitt path algebras of directed graphs with coefficients in a commutative semiring S, as well as establish some f…
