Note on λ- pseudo bi-starlike and bi-convex functions related with sine functions
Year: 2025
Type: article
Abstract: In this paper we introduce two new classes ℬΣλ(μ) of λ-pseudo bi-starlike functions and 𝒦ℬΣλ(μ) of λ-pseudo bi-convex functions. Also, we determine the bounds for |a2| and |a3| where a2, a3 are the initial Taylor coefficients of f∈ℬΣλ(μ) and f∈𝒦ℬΣλ(μ), respectively. Furthermore, we estimate the Fekete-Szegö functionals for the functions in these classes.
