K-product cordial labeling of fan graphs
(Işık University Press, 2023-01)Let f be a map from V (G) to {0, 1, ..., k ? 1} where k is an integer, 1 ? k ? |V (G)|. For each edge uv assign the label f(u)f(v)(mod k). f is called a k-product cordial labeling if |vf (i) ? vf (j)| ? 1, and |ef (i) ? ... -
Local distance irregular labeling of graphs
(Işık University Press, 2023-01)We introduce the notion of distance irregular labeling, called the local distance irregular labeling. We define ? : V (G) ?? {1, 2, . . . , k} such that the weight calculated at the vertices induces a vertex coloring if ... -
Solving existence problems via F-contraction in modified b-metric spaces
(Işık University Press, 2022)In this paper, we introduce a new abstract structure, expanded b-metric, as an natural extension of b-metric. We also define basic topological notions in expanded bmetric to able to investigate the existence of fixed point ... -
A two phase age dependent and two-mutation stochastic model of carcinogenesis
(Işık University Press, 2022)An age dependent and two-mutation stochastic model of carcinogenesis is formulated and studied. In this model, we introduce a fitness age T, (a positive constant) for each cell to divide into two cells. A normal cell if ... -
Whole domination in graphs
(Işık University Press, 2022)In this paper, a new parameter of domination number in graphs is defined which is called whole domination number denoted by ?wh(G). Some bounds of whole domination number and the number of edges depend on it has been ... -
Analysis of a dynamic contact problem for electro-viscoelastic materials with Tresca’s friction
