Bohr inequalities for holomorphic mappings in higher-dimensional complex Banach spaces
Vasudevarao Allu, Raju Biswas, Rajib Mandal
In this paper, we investigates the Bohr phenomenon for holomorphic mappings from the unit ball of a complex Banach space into the closure of the unit polydis…
On the pre-Schwarzian and Schwarzian derivatives of log-harmonic mappings
Raju Biswas, Rajib Mandal
In this paper, we introduce definitions of the pre-Schwarzian and the Schwarzian derivatives for any locally univalent log-harmonic mappings defined in the unit disk $\mathbb{D}=\{…
A unified framework for Bohr-type inequalities using multiple Schwarz functions
