The classes of bipolar single valued neutrosophic graphs
(Işık University Press, 2020)The bipolar single valued neutrosophic graph is the generalization of fuzzy, intuitionistic, bipolar, bipolar intuitionistic graphs. The concept of antipodal bipolar single valued neutrosophic graph (ABSVNG), eccentric ... -
Partition energy of some trees and their generalized complements
(Işık University Press, 2020)Let G = (V, E) be a graph and Pk = {V1, V2, . . . , Vk} be a partition of V . The k-partition energy of a graph G with respect to partition Pk is denoted by EPk (G) and is defined as the sum of the absolute values of ... -
Fuzzy perfect equitable domination excellent trees
(Işık University Press, 2020)A set D of vertices of a fuzzy graph G is a Perfect Dominating set if every vertex not in D is adjacent to exactly one vertex in D. In this paper, we discuss the concept of equitable excellent fuzzy graph, fuzzy equitable ... -
On ruled non-degenerate surfaces with Darboux frame in Minkowski 3-space

Hub-integrity polynomial of graphs
(Işık University Press, 2020)Graph polynomials are polynomials assigned to graphs. Interestingly, they also arise in many areas outside graph theory as well. Many properties of graph polynomials have been widely studied. In this paper, we introduce a ... -
On two identities for I-function
(Işık University Press, 2020)In this research note, two interesting identities involving I-function of one variable introduced by Rathie have been derived. These results enable us to split a particular I-function into the sum of four I-functions. A ... -
Fourth-order accurate method based on half-step cubic spline approximations for the 1d time-dependent quasilinear parabolic partial differential equations
