On Salagean-type harmonic multivalent functions
We define and investigate a new class of Salagean-type harmonic multivalent functions. we obtain coefficient inequalities, extreme points and distortion bounds for the functions in our classes. 2000 Mathematical Subject Classification: 30C45, 30C50, 31A05.
متن کاملHoradam Polynomials Estimates for $lambda$-Pseudo-Starlike Bi-Univalent Functions
In the present investigation, we use the Horadam Polynomials to establish upper bounds for the second and third coefficients of functions belongs to a new subclass of analytic and $lambda$-pseudo-starlike bi-univalent functions defined in the open unit disk $U$. Also, we discuss Fekete-Szeg$ddot{o}$ problem for functions belongs to this subclass.
متن کاملConvolution of Salagean-type Harmonic Univalent Functions
A recent result of Yalcin [9] appeared in Applied Mathematics Letters (2005), concerning the convolution of two harmonic univalent functions in class SH(m,n, α) is improved. AMS (MOS) Subject Classification Codes: 30C45
متن کاملGeneralized Salagean-type harmonic univalent functions
The main purpose of this paper is to introduce a generalization of modified Salagean operator for harmonic univalent functions. We define a new subclass of complex-valued harmonic univalent functions by using this operator ,and we investigate necessary and sufficient coefficient conditions, distortion bounds, extreme points and convex combination for the above class of harmonic univalent functi...
متن کاملACTA UNIVERSITATIS APULENSIS No 12/2006 FRACTIONAL CALCULUS AND SOME PROPERTIES OF SALAGEAN-TYPE K-STARLIKE FUNCTIONS WITH NEGATIVE COEFFICIENTS
We define and investigate a new class of Salagean-type k-starlike functions with negative coefficients. We obtain some properties of this subclass. Furthermore, we give Hadamard product of several functions and some distortion theorems for fractional calculus of this generalized class.
