Exact solution with dust and shell-crossings for LTB inhomogeneous cosmological models
(Işık University Press, 2021)We describe the solution of the Lemaitre-Tolman-Bondi (LTB) inhomogeneous cosmological models for a spherically symmetric with dust and an interaction term modeled as anisotropic pressure is also studied and a differential ... -
Generalization of non-commuting graph of a finite group
(Işık University Press, 2021)In this paper we define the generalized non-commuting graph ?(H,K,L) where H, K and L are three subgroups of a non-abelian group G. Take (H?K?L)\CH(K?L)?CK?L(H) as the vertices of the graph and two distinct vertices x and ... -
Extension of m-polynomial and degree based topological indices for nanotube
(Işık University Press, 2021)The M-polynomial of a graph G(V (G), E(G)) is defined as M(G; u, v) = ? i?j miju?v?, where mij denotes the number of edges xy ? E(G) such that {dx, dy} = {i, j}, where dx, dy denote degree of the vertex x and y in the graph ... -
Geodetic domination integrity in graphs
(Işık University Press, 2021)Reciprocal version of product degree distance of cactus graphs Let G be a simple graph. A subset S ? V (G) is a said to be a geodetic set if every vertex u /? S lies on a shortest path between two vertices from S. The ... -
Neural network modeling of convection heat transfer coefficient for the casson nanofluid
(Işık University Press, 2021)This paper presents applications of Artificial Neural Network (ANN) to develop a mathematical model of magnetohydrodynamic (MHD) flow and heat transfer in a Casson nanofluid. The model equations are solved numerically by ... -
Both a graph and its complement are self-centered with identical radius
(Işık University Press, 2021)We show that a graph and its complement are self-centered with identical radius r only when r = 2. Further, we provide a construction of such a graph for any given order at least eight. -
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 ? ... -
Algorithmic complexity of isolate secure domination in graphs
(Işık University Press, 2021)A dominating set S is an Isolate Dominating Set (IDS) if the induced subgraph G[S] has at least one isolated vertex. In this paper, we initiate the study of new domination parameter called, isolate secure domination. An ... -
Reciprocal version of product degree distance of cactus graphs
(Işık University Press, 2021)The reciprocal version of product degree distance is a product degree weighted version of Harary index defined for a connected graph G as RDD*(G) = Sigma({x, y}subset of V(G) )(d(G)(x).d(G)(y))/d(G)(x,y), where d(G)(x) is ... -
