Univalence of Certain Integral Operators
We study some integral operators and determine conditions for the univalence of these integral operators.
متن کاملOn the Convexity of Certain Integral Operators
In this paper we consider the classes of starlike functions of order α, convex functions of order α and we study the convexity and α-order convexity for some general integral operators. Several corollaries of the main results are also considered.
متن کاملSome Sufficient Conditions for Certain Integral Operators
In this paper, we consider some sufficient conditions for two integral operators to be starlike, close-to-convex and uniformly convex functions defined in the open unit disk. Mathematics subject classification (2000): 30C45.
متن کاملSome Properties for Certain Integral Operators
Abstract. Recently Breaz and Breaz [4] and Breaz et.al[5] introduced two general integral operators Fn and Fα1,...,αn . Considering the classes N(γ), MT(μ, β) and KD(μ, β) we derived some properties for Fn and Fα1,...,αn . Two new subclasses KDFn(μ, β, α1, ..., αn) and KDFα1,...,αn(μ, β, α1, ..., αn) are defined. Necessary and sufficient conditions for a family of functions fj to be in the KDFn...
متن کاملBest Constants for Certain Multilinear Integral Operators
Hilbert’s proof, apart from the determination of the best possible constant π csc(π/p), was published by Weyl [7]. The calculation of the constant, and the integral analogue of Hilbert’s double series theorem (for p = 2) are due to Schur [6]. The generalizations to other p′s of both the discrete and integral versions of this result were discovered later on by Hardy and Riesz and published by Ha...
