A new class BΣλ(γ,κ) of bi-starlike λ-pseudo functions related to the second Einstein function is presented in this paper. c2 and c3 indicate the initial Taylor coefficients of ϕ∈BΣλ(γ,κ), and the bounds for |c2| and |c3| are obtained. Additionally, for ϕ∈BΣλ(γ,κ), we calculate the Fekete–Szegö functional.
