On the topological classification of dynamic equations on time scales

This paper considers the topological classification of non-autonomous dynamic equations on time scales. In this paper we show, by a counterexample, that the trivial solutions of two topologically conjugated systems may not have the same uniform stability. This is contrary to the expectation that two topologically conjugated systems should have the same topological structure and asymptotic behaviors. To counter this mismatch in expectation, we propose a new definition of strong topological conjugacy that guarantees the same topological structure, and in particular the same uniform stability, for the corresponding solutions of two strongly topologically conjugated systems. Based on the new definition, a new version of the generalized Hartman-Grobman theorem is developed. We also include some examples to illustrate the feasibility and effectiveness of the new generalized Hartman-Grobman theorem. (C) 2013 Elsevier Ltd. All rights reserved.
