摘要

在这篇论文中，我们介绍了一个新的类ℒ ∑λ（φ），并确定|a2|和|a3|的界，其中a2，a3是f∈ℒ∑λ（φ）。此外，我们估计了f∈1的Fekete-Szeg¨o泛函ℒ ∑λ（φ）。

On λ-pseudo bi-starlike functions related to some conic domains

In this paper, we introduce a new class ℒ Σ λ (φ) of λ-pseudo bi-starlike functions and determine the bounds for |a2| and |a3| where a2, a3 are the initial Taylor coefficients of f ∈ ℒ Σ λ (φ). Furthermore, we estimate the Fekete-Szeg¨o functional for f ∈ ℒ Σ λ (φ).
