Minimal restrained monophonic sets in graphs
(Işık University Press, 2021)For a connected graph G = (V, E) of order at least two, a restrained monophonic set S of a graph G is a monophonic set such that either S = V or the subgraph induced by V ?S has no isolated vertices. The minimum cardinality ... -
Extending the notion of 3-fold-3-point-splitting from graphs to binary matroids
(Işık University Press, 2021)Slater defined r-fold-n-point-splitting operation on graphs and proved that, if G is an n-connected graph and H is a graph obtained from G by an r-fold-n-pointsplitting, then H is n-connected. In this article we extend ... -

(Işık University Press, 2021)The objective of this paper is to obtain an upper bound of the third order Hankel determinant for the class of multivalent bounded turning functions of order ? (0 ? ? < 1). -
Hosoya polynomial of a multi-bridge graph
(Işık University Press, 2021)Explicit expressions of the Hosoya polynomials of some classes of graphs are known. In this paper we find an explicit expression for the Hosoya polynomial of the multibridge graph. Finally we give some examples of multi-bridge ... -
Radial basis function generated finite difference method for the solution of sinh-Gordon equation
(Işık University Press, 2021)Accuracy of radial basis functions (RBFs) is increased as the shape parameter decreases and produces an ill-conditioned system. To overcome such difficulty, the global stable computation with Gaussian radial basis function-QR ... -
Certain types of graphs in interval-valued intuitionistic fuzzy setting
(Işık University Press, 2021)Interval-valued intuitionistic fuzzy graph (IVIFG) as a generalization of intuitionistic fuzzy graph (IFG) increases its elasticity drastically. In this paper, some important types of IVIFGs such as regular, irregular, ... -
Controlled multipliers with two operators in Hilbert C*-modules
(Işık University Press, 2021)Improving and extending the notion of controlled frames, in this paper, we introduce controlled frames with two operators for Hilbert C*-modules. This generalize controlled frames in Hilbert and Hilbert C*-module. We show, ... -
Fuzzy congruence on M??groups
(Işık University Press, 2021)In this paper, we consider an algebriac structure M?? group, which is a generalization of both the concepts module over a nearring and a gamma nearring, introduced by Satyanarayana [12]. In this paper, we define a fuzzy ... -
