On the Fekete-Szegö problem for concave univalent functions
B. Bhowmik, S. Ponnusamy, K-J. Wirths
We consider the Fekete-Szegö problem with real parameter for the class of concave univalent functions.
On Turán type inequalities for modified Bessel functions
Árpád Baricz, Saminathan Ponnusamy
In this note our aim is to point out that certain inequalities for modified Bessel functions of the first and second kind, deduced recently by Laforgia and Natalini, are in fact eq…
Functional inequalities for modified Bessel functions
Árpád Baricz, Saminathan Ponnusamy, Matti Vuorinen
In this paper our aim is to show some mean value inequalities for the modified Bessel functions of the first and second kinds. Our proofs are based on some bounds for the logarithm…
On some problems of James Miller
B. Bhowmik, S. Ponnusamy, K-J. Wirths
We consider the class of meromorphic univalent functions having a simple pole at and that map the unit disc onto the exterior of a domain which is starlike with respect…
Characterization and the pre-Schwarzian norm estimate for concave univalent functions
B. Bhowmik, S. Ponnusamy, K-J. Wirths
Let denote the class of concave univalent functions in the unit disk $\ID$. Each function maps the unit disk $\ID$ onto the complement of an unbounded convex s…
Coefficient Inequalities for Concave and Meromorphically Starlike Univalent Functions
Bappaditya Bhowmik, Saminathan Ponnusamy
Let $\ID$ denote the open unit disk and $f:\,\ID\TO\BAR\IC$ be meromorphic and univalent in $\ID$ with the simple pole at and satisfying the standard normalization $f(…
