Inequalities generated with Riemann-Liouville fractional integral operator
(Işık University Press, 2019)
The primary objective of this study is to handle new generalized midpoint, trapezoid and Simpson’s type inequalities with the help of Riemann-Liouville fractional integral operator. In order to do this, a new fractional ...
On key exchange method via topological concepts
(Işık University Press, 2019)
Key exchange algorithms such as the Diffie-Hellman method are used to determine a common secret key which will be used in symmetric key algorithms in cryptography. In this paper, we give a key exchange algorithm which ...
An application of factorable surfaces in Euclidean 4−space E⁴
(Işık University Press, 2019)
In the present paper, we consider the factorable surfaces in Euclidean 4-space E⁴. We characterize such surfaces in terms of their Gaussian curvature, Gaussian torsion and mean curvature. Further, we classify flat, ...
On total vertex-edge domination
(Işık University Press, 2019)
In this paper we obtain an improved upper bound of total vertex edgedomination number of a tree. If T is a connected tree with order n, then ????(T) ? m/3 with m = 6[ n/6] and we characterize the trees attaining this upper ...
The Bochner vanishing theorems on the conformal Killing vector fields
(Işık University Press, 2019)
In this paper, the result of the Bochner vanishing theorems, indicating the conditions that every conformal killing vector fields is parallel and there is no nontrivial Conformal Killing vector field, are satisfied under ...
Results on soft Hilbert spaces
(Işık University Press, 2019)
Molodtsov [6] introduced the notion of soft set which can be considered as a new mathematical approach for vagueness. Das and Samanta [8] first defined the soft vector space and soft norm. Yazar and et al. [9] defined the ...
Existence and multiplicity of weak solutions for perturbed Kirchhoff type elliptic problems with hardy potential
(Işık University Press, 2019)
In this paper, we prove the existence of at least three weak solutions for a doubly eigenvalue elliptic systems involving the p-biharmonic equation with Hardy potential of Kirchhoff type with Navier boundary condition. ...
Cooperative two-stage network dea: a goal programming approach
(Işık University Press, 2019-01-05)
In this study, we present a two-stage data envelopment analysis method dealing with efficiency evaluation of decision making units with network structure. The key point of the study is that the suggested model optimizes ...
One-dimensional cutting stock problem with divisible items: a case study in steel industry
(Işık University Press, 2019)
This paper considers the one-dimensional cutting stock problem (1D-CSP) with divisible items, which arises in the steel industries. While planning the steel cutting operations, each item can be divided into smaller pieces, ...
Exponential domination of tree related graphs
(Işık University Press, 2019)
The well-known concept of domination in graphs is a good tool for analyzing situations that can be modeled by networks. Although a vertex in the graph can exert influence on, or dominate, all vertices in its immediate ...
