On the stability of -uniform domains
R. Klén, Y. Li, S. K. Sahoo +1
We study two metrics, the quasihyperbolic metric and the distance ratio metric of a subdomain . In the sequel, we investigate a class of domains, so called…
On Jordan type inequalities for hyperbolic functions
R. Klen, M. Visuri, M. Vuorinen
This paper deals with some inequalities for trigonometric and hyperbolic functions such as the Jordan inequality and its generalizations. In particular, lower and upper bounds for…
Teichmüller's problem in space
R. Klén, V. Todorčević, M. Vuorinen
Quasiconformal homeomorphisms of the whole space Rn, onto itself normalized at one or two points are studied. In particular, the stability theory, the case when the maximal dilatat…
On quasiconformal maps with identity boundary values
Vesna Manojlović, Matti Vuorinen
Quasiconformal homeomorphisms of the unit ball of onto itself with identity boundary values are studied. A spatial analogue of Teichmüller's theorem…
Region of variability for certain classes of univalent functions satisfying differential inequalities
S. Ponnusamy, A. Vasudevarao, M. Vuorinen
In this paper we determine the region of variability for certain subclasses of univalent functions satisfying differential inequalities. In the final section we graphically illustr…
