We consider the unique determination of Riemann zeta function as a solution of its functional equaiton under the condition sharing value. Besides, we show how the Riemann zeta function is uniquely ...

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 ...
