On the δ-chromatic numbers of the Cartesian products of graphs

open access: yesOpen Mathematics
In this work, we study the δ\delta -chromatic number of a graph, which is the chromatic number of the δ\delta -complement of a graph. We give a structure of the δ\delta -complements and sharp bounds on the δ\delta -chromatic numbers of the Cartesian ...

Strong incidence domination in some operations of fuzzy incidence graphs and application in security allocation

open access: yesInternational Journal of Mathematics for Industry
This paper explores operations on fuzzy incidence graphs (FIGs), focusing on join, Cartesian product, tensor product, and composition. Emphasizing strong fuzzy incidence graphs (SFIGs), the study examines strong incidence domination (SID) and the strong ...

Hypo-q-norms on cartesian products of algebras of bounded linear operators on Hilbert spaces

open access: yesExtracta Mathematicae, 2019
: In this paper we introduce the hypo-q-norms on a Cartesian product of algebras of bounded linear operators on Hilbert spaces. A representation of these norms in terms of inner products, the equivalence with the q-norms on a Cartesian product and some ...
