چکیده
For analytic functions f (z) = z p +a p+1 z p+1 +··· in the open unit disk U and a polynomial Q(z) of degree n > 0, the function F(z) = f (z)[Q(z)] β/n is introduced. The object of the present paper is to determine the radius of p-valently strongly starlikeness of order γ for F(z).

Radius of p-valent Strong Starlikeness for Certain Class of Analytic Functions
This paper deals with p-valent strongly starlikeness of the class SP (α,A,B) satisfying the subordination e zf ′(z) f(z) ≺ cos z 1 +Az 1 +Bz + i sin α, f ∈ A, z ∈ ∆, 0 ≤ α < 1, −1 ≤ B < A ≤ 1. We are concerned with computing the radius results for the above mentioned class and the results that we obtained are generalizations of earlier results obtained previously by different authors.

As consequences, sufficient conditions for univalence, starlikeness and strongly starlikeness of certain analyti...
متن کاملCertain New Classes of Analytic Functions Defined by Using the Salagean Operator (dedicated in Occasion of the 70-years of Professor
New classes of analytic functions defined by using the Salagean operator are introduced and studied. We provide coefficient inequalities, distortion theorems, extreme points and radius of close-to-convexity, starlikeness and convexity of these classes.

The main object of the present paper is to derive some results for multivalent analytic functions defined by a linear operators. As a special case of these results, we obtain several sufficient conditions for close-to-convexity and starlikeness of certain analytic functions.
متن کاملRadius Constants for Analytic Functions with Fixed Second Coefficient
Let f(z) = z + ∑(n=2)(∞) (a)n(z) (n) be analytic in the unit disk with the second coefficient a2 satisfying |a2| = 2b, 0 ≤ b ≤ 1. Sharp radius of Janowski starlikeness is obtained for functions f whose nth coefficient satisfies |a(n)| ≤ cn + d (c, d ≥ 0) or |a(n)| ≤ c/n (c > 0 and n ≥ 3). Other radius constants are also obtained for these functions, and connections with earlier results are made.
