Prime labeling in the context of subdivision of some cycle related graphs
(Işık University Press, 2021)A prime labeling on a graph G of order n is a bijection from the set of vertices of G into the set of first n positive integers such that any two adjacent vertices in G have relatively prime labels. The results about prime ... -
The Fekete-Szegö problems for a subclass of m-fold symmetric bi-univalent functions
(Işık University Press, 2021)In this paper, we investigate a new subclass P??? ?m(?, ?) of m-fold symmetric bi-univalent functions. Moreover, for functions of this subclass, we obtain the coefficient estimates of the Taylor-Maclaurin coefficients ... -
Directed pathos middle digraph of an arborescence
(Işık University Press, 2021)A directed pathos middle digraph of an arborescence A?, written Q = DPM(A?), is the digraph whose vertex set V (Q) = V (A?) ? A(A?) ? P(A?), where V (A?) is the vertex set, A(A?) is the arc set, and P(A?) is a directed ... -
Practical stability and boundedness criteria of impulsive differential system with initial time difference
(Işık University Press, 2021)In this paper, an impulsive differential system is investigated for the first time for practical stability and boundedness criteria with respect to initial time difference. The investigations are carried out by perturbing ... -
Some results on vertex-edge neighborhood prime labeling
(Işık University Press, 2021)Let G be a graph with vertex set V (G) and edge set E(G). For u ? V (G), NV (u) = {w ? V (G)|uw ? E(G)} and NE(u) = {e ? E(G)|e = uv, for some v ? V (G)}. A bijective function f : V (G) ? E(G) ? {1, 2, 3, . . . , |V (G) ? ... -
New subclasses of bi-univalent functions of complex order associated with hypergeometric functions
(Işık University Press, 2021)In the present paper, new subclasses of bi-univalent functions of complex order associated with hypergeometric functions are introduced and coefficient estimates for functions in these classes are obtained. Several new (or ... -
Fuzzy super resolving number and resolving number of some special graphs
(Işık University Press, 2021)Resolving number of a graph was introduced by Slater in the year 1975, which is used to navigate the position of the robot uniquely in a graph-structured framework. In this paper, we introduce fuzzy super resolving set, ... -
Edge H-domination in graph
(Işık University Press, 2021)This paper is about edge H-domination of the graph. The edge H-dominating set is defined and the characterization of a minimal edge H-dominating set of the graph with minimum degree 2 is given. The upper bound on the edge ... -
