Abstract

Since Grebogi, Ott, Pelikan and Yorke published "Strange attractors that are not chaotic" in 1984, many works about Strange Nonchaotic Attractors (SNA) have appeared in the literature. The definition of SNA is given in terms of strange attractors and nonchaotic attractors. There are more than one definition of strange attractor and although there is a unique definition of nonchaotic attractors, there are some problems on how to apply it.
This talk will be divided in two parts. In the first one we will give some examples an results of SNA to ilustrate the different definitions we have found in the literarture and their applications. In the second part, we will propose a new definition and discuss it in the light of the published definitions.
This talk is based on a join work with Lluís Alsedà
