- ItemEstimates of Fekete-Szeg¨o Functional of a Sub class of Analytic and Bi-Univalent Functions by Means of Chebyshev Polynomials(2021-02-24) Ayinla Rasheed .O.In this work, a new subclass CΦ(γ, σ, n, t) of analytic and bi-univalent functions is defined by subordination principle and investigated. The initial coefficient bounds and the upper estimates of the Fekete-Szeg¨o functional were obtained using Chebyshev polynomials.
- Itemlitz Determinants for a Subclass of Ana lytic Functions(2021) Ayinla Rasheed .O.; Bello Risikat .A.A new subclass of analytic functions that generalizes some known subclasses of analytic functions was defined and investigated. The bounds for Toeplitz determinants of T_2(2), T_2(3), T_3(1) and T_3(2) were obtained.
