Hölder Continuity of Harmonic Quasiconformal Mappings
Miloš Arsenović, Vesna Manojlović, Matti Vuorinen
We prove that for harmonic quasiconformal mappings -Hölder continuity on the boundary implies -Hölder continuity of the map itself. Our result holds for the class of uniforml…
On Kaluza's sign criterion for reciprocal power series
Árpád Baricz, Jetro Vesti, Matti Vuorinen
T. Kaluza has given a criterion for the signs of the power series of a function that is the reciprocal of another power series. In this note the sharpness of this condition is expl…
On harmonic functions and the Schwarz lemma
David Kalaj, Matti Vuorinen
We study the Schwarz lemma for harmonic functions and prove sharp versions for the cases of real harmonic functions and the norm of harmonic mappings.
Reflections on Ramanujan's Mathematical Gems
G. D. Anderson, M. Vuorinen
The authors provide a survey of certain aspects of their joint work with the late M. K. Vamanamurthy. Most of the results are simple to state and deal with special functions, a top…
