Minimal restrained monophonic sets in graphs
(Işık University Press, 2022)
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 ...
Hub number of generalized middle graphs
(Işık University Press, 2022)
A hub set in a graph G is a set S ⊆ V (G) such that any two vertices outside S are connected by a path whose all internal vertices are members of S. The minimum cardinality of hub set is called hub number. In this paper, ...
Domination number of a bipartite semigraph when it is a cycle
(Işık University Press, 2022)
Semigraph is a generalization of graph, with two or more vertices on edges which allows multiplicity in every concept of graph when it comes to semigraph. When number of vertices on the edges are restricted to two the ...
Coefficient estimates for new subclasses of meromorphic bi-univalent functions associated with linear operatör
(Işık University Press, 2022)
In this paper, we define a new differential linear operator of meromorphic bi-univalent functions class Σʹ, and obtain the estimates for the coefficients |b₀| and |b₁|. Further we pointed out several new or known consequences ...
Edge product cordial labeling of switching operation on some graphs
(Işık University Press, 2022)
Here we discuss and prove that the graphs attained by switching of any vertex with degree two which is adjacent to a vertex with degree two in triangular snake Tm, switching of any vertex with degree one in path Pm for m ...
Extending the applicability of a fourth-order method under Lipschitz continuous derivative in Banach spaces
(Işık University Press, 2022)
We extend the applicability of a fourth-order convergent nonlinear system solver by providing its local convergence analysis under Lipschitz continuous Fréchet derivative in Banach spaces. Our analysis only uses the ...
Approximate fixed point property in IFNS
(Işık University Press, 2022)
In this paper, we define concept of approximate fixed point property of a function and a set in intuitionistic fuzzy normed space. Furthermore, we give intuitionistic fuzzy version of some class of maps used in fixed point ...
Denumerably many positive solutions for rl-fractional order bvp having denumerably many singularities
(Işık University Press, 2022)
In this paper, we consider Riemann-Liouville two-point fractional order boundary value problem having denumerably many singularities and determined sufficient conditions for the existence of denumerably many positive ...
Nonstandard finite difference schemes with application to biological models
(Işık University Press, 2022)
This paper deals with the construction of nonstandard finite difference methods for solving a specific Rosenzweig-MacArthur predator-prey model. The reorganization of the denominator of the discrete derivatives and nonlocal ...
Signed total double Roman dominatıon numbers in digraphs
(Işık University Press, 2022)
Let D = (V, A) be a finite simple digraph. A signed total double Roman dominating function (STDRD-function) on the digraph D is a function f : V (D) → {−1, 1, 2, 3} satisfying the following conditions: (i) P x∈N−(v) f(x) ...
