Estimates for the hyperbolic and quasihyperbolic metrics in hyperbolic regions
Swadesh Kumar Sahoo
In this paper we consider ordinary derivative of universal covering mappings of hyperbolic regions in the complex plane. We obtain sharp bounds for the ratio $|f'(z)|/{\rm…
A note on a class of -valent starlike functions of order beta
Swadesh Sahoo, Navneet Lal Sharma
In this paper we obtain sharp coefficient bounds for certain -valent starlike functions of order , . Initially this problem was handled by Aouf in "M. K. Aouf, On a…
Radius problems associated with pre-Schwarzian and Schwarzian derivatives
S. Ponnusamy, S. K. Sahoo, T. Sugawa
Some of important univalence criteria for a non-constant meromorphic function on the unit disk $\ID$ involve its pre-Schwarzian or Schwarzian derivative. We consider an appr…
Inequalities and geometry of hyperbolic-type metrics, radius problems and norm estimates
Swadesh Kumar Sahoo
We consider certain inequalities among the Apollonian metric, the Apollonian inner metric, the metric and the quasihyperbolic metric. We verify that whether these inequalities…
