dc.description.abstract | In recent years, assorted fascinating properties and characteristics of the many differentsubclasses of analytic univalent functions are consistently investigated. In this work theclass |-fUSs (_; _; _; _; t) [_ _ _ _ 0, 0 _ _ _ 1, _; | _ 0, and#1048576;1 _ jtj _ and#1048576;1, t 61, newline0 _ _ lt 1] of analytic functions with negative coefficients is introduced in the open newlineunit disk U, janj is estimated. Neighborhood properties, partial sums are obtained. newlineIn the other direction the Taylor-Maclaurin series of the coefficients function newlinesatisfies the general subclasses of C_(_; _; t), G_(_; _; t) and L_(_; _; t). The Faber newlinepolynomial expansion has been applied for the function h(z) belongs to C_(_; _; t), newlineG_(_; _; t)and L_(_; _; t). The values of ja2j and ja3j are ensured in the present newlineresearch.This work also consists of the general subclasses of B_(_; l; t), C_(_; l; t) and D_(_; l; t) of bi-univalent Sakaguchi kind of functions, which are expressed in newlineChebyshev polynomials.This Chebyshev polynomials the Ist and IInd kind are exerted newlineto expose the estimation of ja2j and ja3j. Fekete-Szeg¨o form of inequalities for the newlinefunction in these classes have been obtained. Finally as an application of the functions11+z ; 5z+5 and 2z+2 are considered as a transfer function and Chebyshev typeI]low-passfilter is designed to analyse magnitude and phase response. newlineAdditionally the subclasses B(_; ; t), C(; t), P(_; _; t) and Q(; t) are defined in newlinehypergeometric functions. Sufficient condition for[Gaussian] hypergeometric function newlineto be in the subclass of Sakaguchi kind of order _ is obtained. Necessary and Sufficient conditions are provided with additional restrictions. Moreover integral operator related to the hypergeometric function in the open unit disk U is discussed newline | |
