Amenable Actions, Free Products and a Fixed Point Property

We investigate the class of groups admitting an action on a set with an invariant mean. It turns out that many free products admit interesting actions of that kind. A complete characterization of such free products is given in terms of a fixed point property.

Super-Relational Fixed Point Property and Products in Ordered Sets

Super-relational fixed point property for ordered sets is formulated. It is weaker than the strengthened fixed point property and stronger than the product property. It is a long-standing problem whether every ordered set with the fixed point property has the product property. Several attempts have been made which solved the problem for some important classes of ordered sets. What is known may ...

The fixed point property for arc component preserving mappings of non-metric tree-like continua

The main purpose of this paper is to study the fixed point property of non-metric tree-like continua. Using the inverse systems method, it is proved that if X is a non-metric tree-like continuum and if f : X → X is a mapping which sends each arc component into itself, then f has the fixed point property.
