In this article, for the first time by using Caputo-type fractional derivatives, we introduce three
new subclasses of bi-univalent functions associated with bounded boundary rotation in an …

A new class B Σ λ (γ, κ) of bi-starlike λ-pseudo functions related to the second Einstein

In this paper we introduce a new class LΣ (λ; x) of λ-pseudo bi-starlike functions through the
(p, q)-Lucas polynomials and determine the bounds for| a2| and| a3| where a2, a3 are the …
