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…
On the algebraic representation of selected optimal non-linear binary codes
Marcus Greferath, Jens Zumbrägel
Revisiting an approach by Conway and Sloane we investigate a collection of optimal non-linear binary codes and represent them as (non-linear) codes over Z4. The Fourier transform w…
On the Pseudocodeword Redundancy
Jens Zumbragel, Mark F. Flanagan, Vitaly Skachek
We define the AWGNC, BSC, and max-fractional pseudocodeword redundancy of a code as the smallest number of rows in a parity-check matrix such that the corresponding minimum pseudow…
