On strong chain recurrence for maps

Katsuya Yokoi (2015)

Annales Polonici Mathematici

Similarity:

This paper is concerned with strong chain recurrence introduced by Easton. We investigate the depth of the transfinite sequence of nested, closed invariant sets obtained by iterating the process of taking strong chain recurrent points, which is a related form of the central sequence due to Birkhoff. We also note the existence of a Lyapunov function which is decreasing off the strong chain recurrent set. As an application, we give a necessary and sufficient condition for the coincidence...

Chain-finite operators and locally chain-finite operators.

Teresa Bermúdez, Antonio Martinón (1999)

Similarity:

The problem we are concerned with in this research announcement is the algebraic characterization of chain-finite operators (global case) and of locally chain-finite operators (local case).
