"Yarman-36 makam tone-system" for Turkish art music
(Işık University Press, 2014)This study offers a mathematically rigorous, yet straightforward, fixed-pitch tuning strategy to the problem of adequate sounding and notating of essential Turkish makam genera, in contradistinction to the praxis-mismatched ... -
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 ... -
Solving fractional diffusion and fractional diffusion-wave equations by Petrov-Galerkin finite element method
(Işık University Press, 2014)In the last few years, it has become highly evident that fractional calculus has been widely used in several areas of science. Because of this fact, their numerical solutions also have become urgently important. In this ... -
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 ... -
Optimization of renewal input (a, c, b) policy working vacation queue with change over time and bernoulli schedule vacation interruption
(Işık University Press, 2014)This paper presents a renewal input single working vacation queue with change over time and Bernoulli schedule vacation interruption under (a, c, b) policy. The service and vacation times are exponentially distributed. The ... -
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. -
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 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. ... -
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 ... -
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 ... -
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. -
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. -
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 ... -
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 ... -
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 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 ... -

(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 ... -
Estimating coefficients for subclasses of meromorphic bi-univalent functions associated with linear operator
(Işık University Press, 2014)In this paper we define a differential linear operator, applying it on the subclasses H??B (?, n, ?) of meromorphic starlike bi-univalent functions of order ?, and H?˜ ?B (?, n, ?) of meromorphic strongly starlike bi-univalent ... -
Differential subordinations using ruscheweyh derivative and S?l?gean operator
(Işık University Press, 2014)In the present paper we study the operator defined by using the Ruscheweyh derivative Rm f(z) and the S?l?gean operator Sm f(z), denoted Lm? : An ? An, Lm? f(z) = (1??)Rm f(z)+?Sm f(z), z ? U, where An = {f ? H(U) : f(z) ...
