STARLIKENESS AND SUBORDINATION PROPERTIES OF A LINEAR OPERATOR
《Acta Mathematica Scientia》2014年第5期1446-1460,共15页Samaneh Gholizadeh HAMIDI Suzeini Abdul HALIM Janusz SOKóL 
In this paper, we introduce a new class of p-valent analytic functions defined by using a linear operator Lαk . For functions in this class Hαk （p,λ;h） we estimate the coefficients. Furthermore, some subordinatio...

ON CRITERIA FOR STARLIKENESS AND CONVEXITY OF ANALYTIC FUNCTIONS
《Acta Mathematica Scientia》2004年第4期597-602,共6页Vikramaditya Singh Nikola Tuneski 
In this paper the authors study (1-γ+zf(?)(z)/f'(z))/(zf'(z)/f(z)) as a criteria for starlikeness and convexity. Sharp upper bound of |α2| and of the Fekete-Szego functional |α3-μα22| is given for a class of anal...
