Content available remote Some properties of a class of analytic functions
Patel J., Mohanty A. K.
Demonstratio Mathematica
|
2002
|
Vol. 35, nr 2
273-286
EN
We give, among other results, some criteria for p-valence of functions f(z) = zp+ap+izp+1 + ... analytic in the unit disc.

Content available remote Some applications of differential subordination to a class of analytic functions
Patel J., Sahoo P.
Demonstratio Mathematica

2002
|
Vol. 35, nr 4
749-762
EN
We introduce (and investigate various properties and characteristics of) certain class Hn (A, B) of analytic functions in the open unit disc by using the techniques of Briot-Bouquet differential subordination. Relevant connections of the results obtained here with the earlier works are pointed out.

z. 25 [190]
151-165
EN
The object of the present paper is to introduce two subclasses Bk,p (a, c) and Ck,p (a, c) of analytic functions in the open unit disc involving a linear operator [...] (a, c) and derive some properties of these classes.

On certain subclasses of meromorphically p-valent functions
Patel J., Sahoo P.
Zeszyty Naukowe Politechniki Rzeszowskiej. Matematyka
|
2001

z. 25 [190]
139-149
EN
The object of the present paper is to investigate some properties and characteristics of the subclasses summation n,p (alpha) and [...]n,p (alpha) of meromorphically p-valent functions in the annulus U ={z :0 <\z\ <1}. We also study certain integrals of functions belonging to these classes.

2000
|
z. 24 [181]
79-85
EN
Let A (p) denote the class of functions f (z) =zp+[summation]infinity/k=p+1akzk analytic in the unit disc E. In this paper, we obtain a condition for starlikeness of the integral operator [...].

On a class of analytic functions with negative coefficients
Patel J., Sahoo P.
Zeszyty Naukowe Politechniki Rzeszowskiej. Matematyka
|
2000
|
z. 24 [181]
87-101
EN
In this paper, we introduce and study some classes of analytic functions in the unit disk. Comparable results, results concerning the Quasi-Hadamard product and distortion theorems involving fractional calculus of functions belonging to the class are obtained.
