Abstract: |
In the paper, we mainly investigate Bohr-type inequalities for the analytic self-mappings and their derivative functions. By utilizing new coefficients inequalities, we establish three new Bohr-type inequalities, and obtain corresponding sharp Bohr-radius, which refine the results of Bappaditya Bhowmik and Nilanjan Das (arXiv:1911.06597v1[math.CV], November 2019). |
