Some properties of certain subclasses of meromorphic p-valent integral operators
(Işık University Press, 2014)
For meromorphic p-valent function of the form fi(z) = 1−α (z−w)p + ∑∞ n=2 a i n(z−w)n, α < 1, which are analytic in the punctured unit disk z : 0 < |z −w| < 1 with a pole of order p at w, a class Γp β (ζ1, ζ2; γ) is ...
On a criterion for multivalent harmonic functions
(Işık University Press, 2014)
For normalized harmonic functions f(z) = h(z) + g(z) in the open unit disk, a criterion on the analytic part h(z) for f(z) to be p-valent and sense-preserving is discussed. Furthermore, several illustrative examples and ...
Domination integrity of total graphs
(Işık University Press, 2014)
The domination integrity of a simple connected graph G is a measure of vulnerability of a graph. Here we determine the domination integrity of total graphs of path Pn, cycle Cn and star K1,n.
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 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 ...
On a new subclass of harmonic meromorphic functions wıth fixed residue ξ
(Işık University Press, 2014)
We use the differential operator Dn,µ λ,δ,φ to introduce a new class SHn,γ,β,ξ λ,δ,φ,µ (w, k, α) of meromorphic harmonic functions with fixed residue ξ in Uw. Then we give the coefficient estimates, distortion theorem and ...
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 ...
On an extension of kummer-type II transformation
(Işık University Press, 2014)
In the theory of hypergeometric and generalized hypergeometric series, Kummer’s type I and II transformations play an important role. In this short research paper, we aim to establish the explicit expression of e⁻ x/2 2F2 ...
New sufficient conditions for starlike and convex functions
(Işık University Press, 2014)
Let A be the class of analytic functions f(z) in the open unit disc. Applying the subordination, some sufficient conditions for starlikeness and convexity are discussed.
