Recent results on iteration theory: iteration groups and semigroups in the real case

MC Zdun, P Solarz - Aequationes mathematicae, 2014 - Springer
In this survey paper we present some recent results in the iteration theory. Mainly, we focus
on the problems concerning real iteration groups (flows) and semigroups (semiflows) such …

On fractional iterates of a Brouwer homeomorphism embeddable in a flow

Z Leśniak - Journal of mathematical analysis and applications, 2010 - Elsevier
We present a method for finding continuous (and consequently homeomorphic) orientation
preserving iterative roots of a Brouwer homeomorphism which is embeddable in a flow. To …

On the structure of Brouwer homeomorphisms embeddable in a flow

Z Leśniak - Abstract and Applied Analysis, 2012 - Wiley Online Library
We present two theorems describing the structure of the set of all regular points and the set
of all irregular points for a Brouwer homeomorphism which is embeddable in a flow. The …

The embedding problem in iteration theory

MC Zdun - ESAIM: Proceedings and Surveys, 2014 - esaim-proc.org
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 …

On strongly irregular points of a Brouwer homeomorphism embeddable in a flow

Z Leśniak - Abstract and Applied Analysis, 2014 - Wiley Online Library
We study the set of all strongly irregular points of a Brouwer homeomorphism f which is
embeddable in a flow. We prove that this set is equal to the first prolongational limit set of …

On properties of the set of invariant lines of a Brouwer homeomorphism

Z Leśniak - Journal of Difference Equations and Applications, 2018 - Taylor & Francis
We present properties of sets of invariant lines for Brouwer homeomorphisms which are not
necessarily embeddable in a flow. Using such lines we describe the structure of equivalence …

On the Topological Conjugacy of Brouwer Flows

Z Leśniak - Bulletin of the Malaysian Mathematical Sciences …, 2019 - Springer
We study the problem of topological conjugacy of Brouwer flows. We give a sufficient and
necessary condition for Brouwer flows to be topologically conjugate. To obtain this result we …
