In this paper, we introduce a new class of functions which are analytic and uni-valent with negative coefficients defined by using a certain fractional calculus and fractional calculus integral operators. Characterization property,the results on modified Hadamard product and integrals transforms are discussed. Further, distortion theorem and radii of(More)
2009 recently introduced a new generalized derivative operator μ n,m λ1,λ2 , which generalized many well-known operators studied earlier by many different authors. In this present paper, we shall investigate a new subclass of analytic functions in the open unit disk U {z ∈ C : |z| < 1} which is defined by new generalized derivative operator. Some results on(More)

In this article, a certain differential operator , () k p S f z α,β,l,δ and a subclass () n, p p S , α,β,δ,l for analytic functions with positive coefficients of the form ∑ ∞ + = + = 1) (p n n n p z a z z f are introduced. Some properties such as the coefficients inequalities, distortion theorem, radii of starlikeness and convexity, closure theorems and(More)
