Learn about function notation, how to find an inverse function by changing the subject, and how to work with composite functions.

Coefficient bounds for functions with a positive real part are used in a rather novel way to find sharp bounds for the first six coefficients of a function which is inverse to a regular normalized ...

In the present study, we consider two subclasses of starlike and convex functions, denoted by S ℬ * and 𝐶ℬ respectively, associated with a bean-shaped domain. Further, we estimate certain sharp ...
