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 ...
Extensions for certain subordination relations
(Işık University Press, 2014)
For some complex number ? which has a positive real part, a certain subordination relation concerned with the Bernardi integral operator I? was proven by D. J. Hallenbeck and St. Ruscheweyh (Proc. Amer. Math. Soc. 52(1975), ...
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 ...
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?? (z?w)p + ?? n=2 a i n(z?w)n, ? < 1, which are analytic in the punctured unit disk z : 0 < |z ?w| < 1 with a pole of order p at w, a class ?p ? (?1, ?2; ?) 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 ...
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.
