On a New Class of Concave Bi-Univalent Functions Associated with Bounded Boundary Rotation

Mathematics
In this research article, we introduce a new subclass of concave bi-univalent functions associated with bounded boundary rotation defined on an open unit disk. For this new class, we make an attempt to find the first two initial coefficient bounds.
