We establish sharp estimates for the generalized Zalcman functional corresponding to the index for normalized starlike mappings of order and normalized quasi-convex mappi…
Bohr-type inequalities for certain integral transforms of operator-valued analytic functions on shifted disc
Goutam Haldar, Kawsar Ali, Sujoy Majumder +1
In this paper, we investigate Bohr-type inequalities for certain integral transforms of some bounded holomorphic operator-valued functions defined on a shifted disc. More precisely…
Bohr type inequalities with one parameter for the class of self analytic maps on unit disc
Goutam Haldar, Rakesh Sarkar, Sujoy Majumder +1
We investigate Bohr-type inequalities for bounded analytic functions, particularly in the presence of a parameter or under convex combination structures. Most of our findings are s…
