Diameters of commuting graphs of matrices over semirings

open access: yes, 2010
We calculate the diameters of commuting graphs of matrices over the binary Boolean semiring, the tropical semiring and an arbitrary nonentire commutative semiring.

Proving Termination of Graph Transformation Systems using Weighted Type Graphs over Semirings

open access: yes, 2015
We introduce techniques for proving uniform termination of graph transformation systems, based on matrix interpretations for string rewriting. We generalize this technique by adapting it to graph rewriting instead of string rewriting and by generalizing ...

Multiplicativity of permanents over matrix semirings

open access: yesThe Electronic Journal of Linear Algebra
In this paper, we investigate the conditions for the multiplicativity of the permanent over a matrix semiring. We prove that if $S$ is either a commutative antiring or a commutative semiring where the set $V(S)$ of all additively invertible elements coincides with the set of all nilpotents, then the permanent is multiplicative on the group of ...
