Length Distortion Of Curves Under Meromorphic Univalent Mappings
Bappaditya Bhowmik, Deblina Maity
Let be a conformal (analytic and univalent) map defined on the open unit disk $\D$ of the complex plane $\IC$ that is continuous on the semi-circle $\partial \D^{+}=\{z\in\IC:|…

Landau-type Theorem and Bloch constant for elliptic harmonic mappings
Bappaditya Bhowmik, Sambhunath Sen
In this article, we obtain certain estimates for the Taylor coefficients of -elliptic harmonic mappings and using these estimates, we prove a Landau-type theorem for these…
