We consider a flow of free mappings defined on the plane. We prove that the boundary of
every equivalence class of a certain equivalence relation is a union of orbits and that at most …

This is a survey paper on selected topics concerning the embeddability of given mappings in
real flows. Particular attention will be paid to the relationship between the problem of the …

Let D be a topological space. A family of homeomorphisms {/' : t 6 R} defined on D is said to
be a continuous iteration group if Page 1 Annales Mathematicae Silesianae 8. Katowice …

Let X be a topological space, G be a right topological group (ie a group endowed with a
topology under which for every a∈ G the map x↦ xa is continuous) and 𝒮 be a set of self …

We consider the problem of determining all continuous iteration groups {ft: t∈ R} of a free
mapping f. Some of free mappings which are not Sperner homeomorphisms are considered …
