A question on common fixed points
1999The authors give a partial answer to the following problem: Let \(X\) be a compact space with the fixed point property and \({\mathcal F}\) a family of continuous mappings from \(X\) to \(X\) such that \(|{\mathcal F}|\geq{\mathfrak c}\). In which conditions on \({\mathcal F}\) and \(X\) there is a subfamily \({\mathcal F}_0\subset{\mathcal F}\) of ...

Common Fixed Points of Nonlinear Contractions
Acta Mathematica Hungarica, 1998In der vorliegenden Arbeit werden Paare von Selbstabbildungen eines vollständigen metrischen Raumes betrachtet und hinreichende Bedingungen vom Kontraktionstyp angegeben, die die Existenz und Unität eines gemeinsamen Fixpunktes sichern. Ist \(\Phi\) die Menge aller Funktionen \(\varphi:[0,\infty)\to[0,\infty)\), die rechtsseitig stetig sowie nicht ...

A problem on common fixed points
Mathematics Seminar Notes, 1983The author discusses the following problems: (1) Let f and g be selfmappings of a metric space (X,d). What can we say about the existence of common fixed points of f and g if they satisfy \(d(fx,gy)\leq \alpha \max \{d(x,gy),d(y,fx)\}\) for all x,y\(\in X\) and for some \(\alpha\in (0,1)?\) (2) If f and g satisfy any one of the definitions 149, 174 ...
