pplications of generalized Ruscheweyh derivative to univalent functions with finitely many coefficients
Journal Title: Surveys in Mathematics and its Applications - Year 2009, Vol 4, Issue 0
Abstract
By making use of the generalized Ruscheweyh derivative, the authors investigate several interesting properties of certain subclasses of univalent functions having the form<center> f(z) = z - Σ<SUB>n=2..m</SUB> ((1 - β) e<SUB>n</SUB>) / ((1 - nβ + α(1-n)) B<SUB>1</SUB><SUP>λ, μ</SUP>(n)) z<SUP>n</SUP> - Σ<SUB>k=m+1..∞</SUB> a<SUB>k</SUB>z<SUP>k</SUP>.</center>

On certain Baskakov-Durrmeyer type operators
This paper is a study of the degree of approximation by the linear combinations of the derivatives of certain Durrmeyer type integral modification of the Baskakov operators in terms of the higher order modulus of smoothn...
A class of analytic functions based on convolution
We introduce a class <I>TS</I><SUB>p</SUB><SUP>g</SUP>(α) of analytic functions with negative coefficients defined by convolution with a fixed analytic function g(z)=z+<I>Σ</I...
Fixed time impulsive differential inclusions
In the paper we study weak and strong invariance of differential inclusions with fixed time impulses and with state constraints.We also investigate some properties of the solution set of impulsive system without state co...

Special Features In Turbulent Mixing. Comparison between Periodic and Non Periodic Case
After hundreds of years of stability study, the problems of flow kinematics are far from complete solving. A modern theory appears in this field: the mixing theory. Its mathematical methods and techniques developed the s...
