A Common Fixed Point Theorem with Applications

Journal of Optimization Theory and Applications, 2013
Let \(X\) be a nonempty compact convex subset of a locally convex Hausdorff topological vector space. The main result is that a family \(\{T_i: X\rightrightarrows X\}_{i\in I}\) of closed set-valued mappings with nonempty convex values has a common fixed point if, for each nonempty finite subset \(J\) of the index set \(I\), the mapping \(S_J: X ...

A question on common fixed points

1999
The 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, 1998
In 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, 1983
The 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 ...
