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 ... -
Decoding of orbit codes
(Işık University Press, 2019)Subspace codes have an important role to correct errors and erasures for random network coding. Orbit codes are a family of constant dimension subspace codes and they are interesting for their error correction. In this ... -
Ramsey numbers for class of edgeless, complete and star graphs
(Işık University Press, 2019)For any graph class G of any two positive integers i and j, the Ramsey number RG(i, j) is the smallest integer such that every graph in G on atleast RG(i, j) vertices has a clique of size i or an independent set of size ... -
A dynamical analysis of the virus replication epidemic model
(Işık University Press, 2019)In this article, the stability and the computational algebraic properties of a virus replication epidemic model is investigated. The model is represented by a three dimensional dynamical system with six parameters. The ... -
A new generalization of Ostrowski type inequalities on arbitrary time scale
(Işık University Press, 2019)In this paper, a new generalization of Ostrowski type inequalities for twice differentiable mappings on time scales and some other interesting inequalities as special cases are given. -
Tauberian theorems for the product of borel and logarithmic methods of summability
(Işık University Press, 2019)In this paper, we show that if a sequence is summable by the product method (B)(l, k), then it is also summable by the logarithmic method (l, k), provided two-sided conditions of Hardy-type are satisfied. We also obtain ... -
Interval sheffer stroke basic algebras
(Işık University Press, 2019)In this paper we deal with Sheffer stroke basic algebras A = (A; |), and we define the operations |a, |?, |?? for any elements a, b ? A in such a way that ([a, 1]; |a), ([0, b]; |? ), ([a, b]; |??) become also Sheffer ... -
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 ... -
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, ... -
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 ... -
On some new inequalities for s-convex functions
(Işık University Press, 2019)In this paper, we establish a few new generalization of Hermite-Hadamard inequality using s−convex functions in the 2nd sense. For this purpose we used some special inequalities like Hölder’s. -
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 ... -
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 ... -
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 ... -
On new conformable fractional integral inequalities for product of different kinds of convexity
(Işık University Press, 2019)Certain Hermite-Hadamard type inequalities involving various fractional integral operators for products of two functions have, recently, been presented. We aim to establish several Hermite-Hadamard type inequalities for ... -
A new subclass of bi-univalent functions defined by q-derivative
(Işık University Press, 2019)In this investigation we introduce, by making use of q−derivative operator, a new subclass which are an extension of some well-known subclasses of bi-univalent functions. Also, we give the upper bounds for the coefficients ... -
New refinements and integral inequalities for concave functions
(Işık University Press, 2019)In this paper, we establish new refinements and integral inequalities including concave functions. The reason why we choose the concave functions in this study is that the methods we use are applicable to these functions. ... -
Inequalities for convex functions on time scales
(Işık University Press, 2019)In this paper, we presented ostrowski type ∆−integral inequalities for convex functions. Also we give some results for continuous and discrete choises of time scales. -
Results of some separation axioms in supra soft topological spaces
(Işık University Press, 2019)In this paper, we define separability axioms in supra soft topological spaces by using the soft point given in [1, 3] and investigate some of their characterizations. -
Mathematical modeling of the dependence of heat distribution on direction in surface texturing of continuous carbon fibre reinforced epoxy composites by Nd.Yag Laser
(Işık University Press, 2019)Major developments, especially in the aircraft, automobile and energy sectors, have led to the need to use highly featured new materials used in these fields . Carbon fiber reinforced plastics (CFRP) have been used frequently ...
