Fixed points of contractive set valued mappings with set valued domains on a metric space with graph
(Işık University Press, 2014)
In this article we consider general contractive mappings of the form F : CB(X) ? CB(X), where CB(X) is the set of all nonempty closed and bounded subsets of a complete metric space X endowed with a graph G. We prove some ...
On trigonometric approximation in the space lp(x)
(Işık University Press, 2014)
In this paper we have introduced two new class of numerical sequences, named almost monotone decreasing (increasing) upper second mean sequences. Moreover, we have presented some results on trigonometric approximation of ...
On the solutions of fuzzy fractional differential equation
(Işık University Press, 2014)
In this paper the exact and the approximate solutions of fuzzy fractional differential equation, in the sense of Caputo Hukuhara differentiability, with a fuzzy condition are constructed by using the fuzzy Laplace transform. ...
Harmonic mappings related to the convex functions
(Işık University Press, 2014)
The main purpose of this paper is to give the extent idea which was introduced by R. M. Robinson [5]. One of the interesting application of this extent idea is an investigation of the class of harmonic mappings related to ...
Some results on a subclass of harmonic mappings of order alpha
(Işık University Press, 2014)
Let SH be the class of harmonic mappings defined by SH = { f = h(z) + g(z)| h(z) = z + ?? n=2 anz?, g(z) = b1z + ?? n=2 bnz?, b1 < 1 } where h(z) and g(z) are analytic. Additionally f(z) ? SH(?) ? | zh? (z) ? zg?(z) h(z) ...
Sufficient conditions for generalized Sakaguchi type functions of order ?
(Işık University Press, 2014)
In this paper, we obtain some sufficient conditions for generalized Sakaguchi type function of order ?, defined on the open unit disk. Many interesting outcomes of our results are also calculated.
Free surface flow over a triangular depression
(Işık University Press, 2014)
Two-dimensional steady free-surface flows over an obstacle is considered. The fluid is assumed to be inviscid, incompressible and the flow is irrotational. Both gravity and surface tension are included in the dynamic ...
On a new subclass of harmonic meromorphic functions wıth fixed residue ?
(Işık University Press, 2014)
We use the differential operator Dn,µ ?,?,? to introduce a new class SHn,?,?,? ?,?,?,µ (w, k, ?) of meromorphic harmonic functions with fixed residue ? in Uw. Then we give the coefficient estimates, distortion theorem and ...
On certain classes of univalent meromorphic functions associated with integral operators
(Işık University Press, 2014)
This paper illustrates how some inclusion relationships of certain class of univalent meromorphic functions may be defined by using the linear operator. Further, a property preserving integrals is considered for the final ...
Approximate optimality conditions
(Işık University Press, 2014)
We propose in this paper a systematic study which is a variational approach of approximate optimality conditions in terms of Ekeland’s variational principle and some of its applications. Using a generalised differentiati ...
