Independent domination number of graphs through vertex switching
(Işık University Press, 2024-04)Let G = (V, E) be a graph with vertex set V and edge set E. An independent dominating set S of G is a subset of V with the property that every vertex in V ? S is adjacent to some vertex in S and no two vertices within S ... -
Modeling internet access at home by fractional calculus and a correlation analysis with human development index
(Işık University Press, 2024-04)In this study, we modeled broadband internet access at home data and investigated the relationship between the human development index and internet access in countries. The broadband Internet access at home is modeled using ... -
New vertex-edge sombor, Nirmala and Misbalance indices

On almost convergence of fuzzy variables
(Işık University Press, 2024-04)In this paper, within framework credibility theory, we examine several notions of convergence and almost convergence of fuzzy variable sequences. We investigate relations between these notions. Utilizing fuzzy variables, ... -
On edge irregularity strength of ladder related graphs
(Işık University Press, 2024-04)For a simple graph G, a vertex labeling ? : V (G) ? {1, 2, . . . , k} is called k-labeling. The weight of an edge xy in G, written w?(xy), is the sum of the labels of end vertices x and y, i.e., w?(xy) = ?(x) + ?(y). A ... -
