Revan weighted PI index on some product of graphs
(Işık University Press, 2021)
In chemical graph thoery, PI index is an additive topological index which has been used to measure the characteristics of chemical compounds. In this paper we introduce the weighted version of PI index of graph called the ...
Vertex coloring edge weightings of some square graphs
(Işık University Press, 2021)
A k-edge-weighting w of a graph G is an assignment of integer weight, w(e) ? {1, 2, . . . , k}, to each edge e. A k-edge-weighting w induces a vertex coloring c by defining c(u) = P u?e w(e) for every u ? V (G), where u ? ...
On 2-absorbing fuzzy ideals of commutative semirings
(Işık University Press, 2021)
The purpose of this paper is to introduce and study 2-absorbing fuzzy ideals of commutative semirings. Some basic operations on them are defined and some of its characterizations are obtained.
