In the present investigation, we define two new subclasses of analytic and m-fold symmetric
bi-univalent functions defined by a linear combination in the open unit disk U. Furthermore …

In the present investigation the authors obtain upper bounds for the second Hankel
determinant H 2 (2) of the classes bi-starlike and bi-convex functions of order β, represented …

In the present paper, we introduce and investigate a new class of analytic and bi-univalent
functions f (z) in the open unit disk U. For this purpose, we make use of a linear combination …

In this work, we introduce and investigate a subclass H h, p Σm (τ, γ) of analytic and bi-
univalent functions when both f (z) and f− 1 (z) are m-fold symmetric in the open unit disk U …

In this work, we introduce two new subclasses SΣm (α, λ) and SΣm (β, λ) of Σm consisting of
analytic and m-fold symmetric bi-univalent functions in the open unit disc U. Furthermore, for …
