The busy beaver function is unpredictable. But now, after more than 40 years, the fifth value of the function has been revealed ...

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 ...
