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 twosided conditions of Hardytype 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, ᵇ, ᵇₐ for any elements a, b ∈ A in such a way that ([a, 1]; a), ([0, b]; ᵇ ), ([a, b]; ᵇₐ) become also Sheffer ... 
On total vertexedge 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 γͭᵥₑ(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 4space 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 sconvex functions
(Işık University Press, 2019)In this paper, we establish a few new generalization of HermiteHadamard inequality using s−convex functions in the 2nd sense. For this purpose we used some special inequalities like Hölder’s. 
Inequalities generated with RiemannLiouville 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 RiemannLiouville 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 DiffieHellman 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 HermiteHadamard type inequalities involving various fractional integral operators for products of two functions have, recently, been presented. We aim to establish several HermiteHadamard type inequalities for ... 
A new subclass of biunivalent functions defined by qderivative
(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 wellknown subclasses of biunivalent 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.
