Vaccination of children – summary and conclusions from a systematic review The full review can be found in Acta Pædiatrica 2010; 99: s461 Sven-Arne Silfverdal, Lennart Nilsson, Margareta Blennow, Rose-Marie Carlsson, Lars Å Hanson, Anders Lindberg, Lars Lindquist, Margaretha Magnusson, Anders Norlund, Olof Nyrén, Per Olcén, Patrick Olin, Juliette Säwe, Ann Söderström, Birger Trollfors, Åke Örtq...
Important and interesting results which are already known such as those by Pólya and Schoenberg in (1958), Başgöze et al. in (1970), and Ali in (1973), and which are related to convex maps of the unit disc are presented in this note by a more general, unified, and different method. The method considers the product of a nontrivial multiplier with the Norlund means, and shows how the known result...
