The eigenvalue problem for fuzzy diffusion operators
(Işık University Press, 2020)This paper deals with the eigenvalues of a boundary value problem for a second order fuzzy differential equation. We consider the fuzzy differential operator and give the properties of the eigenvalues of the problem for ... -
Total colorings of core-satellite, cocktail party and modular product graphs
(Işık University Press, 2020)A total coloring of a graph G is a combination of vertex and edge colorings of G. In other words, is an assignment of colors to the elements of the graph G such that no two adjacent elements (vertices and edges) receive a ... -

Bounds for the sum of cubes of vertex degrees of splice graphs
(Işık University Press, 2020)Some chemically interesting graphs can be derived from simpler graphs by some graph operations. One of the most relevant among these interesting graphs is named as splice graphs. They are related to RNA sequencing and ... -
Laceability properties in edge tolerant corona product graphs
(Işık University Press, 2020)A connected graph G is termed Hamiltonian-t-laceable if there exists in it a Hamiltonian path between every pair of vertices u and v with the property d(u, v) = t, 1 ≤ t ≤ diam(G), where t is a positive integer. The corona ... -
Korteweg-de Vries-Burgers (KDVB) equation with Atangana-Baleanu derivative with fractional order
(Işık University Press, 2020-02-13)In this work, we examine the Korteweg–de Vries–Burgers equation with two perturbation’s levels to the concepts of fractional differentiation with no singularity. The Korteweg–de Vries–Burgers equation was constructed using ... -
Edge irregular reflexive labeling for star, double star and caterpillar graphs
(Işık University Press, 2020)A graph labeling is an algorithm that assignment the labels, traditionally represented by integers, to the edges or vertices, or both, of a network(graph) G. Formally, given a graph G = (V, E), a vertex labeling is a ... -
