چکیده
Abstract In this paper, we obtain the bounds of initial logarithmic coefficients for functions in classes $${\mathcal {S}}_S^*$$ S ? and {K}}_S$$ K which are starlike with respect to symmetric points convex points, respectively. our research, use a different approach than usual one coeffcients f expressed by corresponding positive real part. what follows, express Schwarz functions. proofs, apply some inequalities these obtained Prokhorov Szynal, Carlson Efraimidis. This offers additional benefit. many cases, it is easily possible predict exact result select extremal It case .

Starlike Functions of order α With Respect To 2(j,k)-Symmetric Conjugate Points
In this paper, we introduced and investigated starlike and convex functions of order α with respect to 2(j,k)-symmetric conjugate points and coefficient inequality for function belonging to these classes are provided . Also we obtain some convolution condition for functions belonging to this class.
متن کاملInitial coefficients of starlike functions with real coefficients
The sharp bounds for the third and fourth coefficients of Ma-Minda starlike functions having fixed second coefficient are determined. These results are proved by using certain constraint coefficient problem for functions with positive real part whose coefficients are real and the first coefficient is kept fixed. Analogous results are obtained for a general class of close-to-convex functions

We introduce new subclasses S σ,s k λ, δ, φ and K σ,s k λ, δ, φ of analytic functions with respect to k-symmetric points defined by differential operator. Some interesting properties for these classes are obtained.
متن کاملA Class of Harmonic Starlike Functions with Respect to Symmetric Points Associated with the Srivastava–wright Generalized Hypergeometric Function
Making use of Srivastava-Wright operator we introduced a new class of complexvalued harmonic functions with respect to symmetric points which are orientation preserving, univalent and starlike. We obtain coefficient conditions, extreme points, distortion bounds, convex combination. Mathematics subject classification (2010): 30C45.
