In this paper, we introduce and investigate each of the following subclasses: S-g(gimel, gamma) and K-g(gimel,gamma,m;u) (0 <= gimel <= 1;u is an element of R / (-infinity, -1];m is an element of N /functions) of analytic functions of complexorder gamma is an element of C \ functions, g : U -> C being some suitably constrained convex function in the open unit disk U. We obtain coefficient bounds and coefficient estimates involving the Taylor-Maclaurin coefficients of the function f(z) when f(z) is in the class S-g(gimel,-gamma) or in the class K-g(gimel,gamma,m;u). The various results, which are presented in this paper, would generalize and improve those in related works of several earlier authors.

The main object of this present paper is to investigate the problem of majorization for certain classes of analytic functions of complexorder associated associated with the Dziok-Srivastava and the Srivastava Wright convolution operators. Moreover we point out some new or known consequences of our main result.
In this paper, we introduce and study some new subclasses of analytic functions defined by the combination of Al-Oboudi and Ruscheweyh differential operators, and obtain coefficient estimates and Fekete-Szego inequali...

In this paper, we introduce and study some new subclasses of analytic functions defined by the combination of Al-Oboudi and Ruscheweyh differential operators, and obtain coefficient estimates and Fekete-Szego inequalities for these new subclasses. The results presented in this paper improve the recent work of Kanas and Darwish (Appl Math Lett 23(7), 777-782, 2010).
