Multivalent functions and QK spaces
We give a criterion for q-valent analytic functions in the unit disk to belong to Q K , a Möbius-invariant space of functions analytic in the unit disk in the plane for a nonde-creasing function K : [0, ∞) → [0, ∞), and we show by an example that our condition is sharp. As corollaries, classical results on univalent functions, the Bloch space, BMOA, and Q p spaces are obtained. 1. Introduction....
متن کاملFurther Generalization of Gamma and Beta Functions
The objective of this paper is to define and study further generalization of extended gamma, extended beta and extended hypergeometric functions. Closed form representation of the generalized extended gamma function is derived in the form of Meijer’s G-function. Some of their properties and special cases are also derived. These functions have applications in probability theory, reliability, ast...
متن کاملHuman Observation Based Generalized Gamma Functions
This paper describes an accurate method to obtain the Tone Reproduction Curve (TRC) of display devices without using a measurement device. It is an improvement of an existing technique based on human observation, solving its problem of numerical instability and resulting in functions in log–log scale which correspond better to the nature of display devices. We demonstrate the effiency of our te...
متن کاملA Class of Generalized Gamma Functions
In this paper, we study the holomorphic function defined by the infinite product Γa,r(s) = ∏ n≥0(1 + 1 a+nr ) (1 + s a+nr ) which generalize Euler’s definition in the sense that Γ(s) = Γ1,1(s) s . We obtain analogues of the Gauss multiplication formula, complement formula for functions Γa,r(s).

متن کاملContra $beta^{*}$-continuous and almost contra $beta^{*}$-continuous functions
The notion of contra continuous functions was introduced and investigated by Dontchev. In this paper, we apply the notion of $beta^{*}$-closed sets in topological space to present and study a new class of functions called contra $beta^{*}$-continuous and almost contra $beta^{*}$-continuous functions as a new generalization of contra continuity.
