“…However, it can not be extended to any C 2 as well as C 1 diffeomorphism whose derivative is a function of bounded variation, see in [8]. Subsequently, similar phenomena for high dimensional diffeomorphisms were studied by several authors, for example [22,18,30,4,31,27]. Also, for unimodal as well as multimodal maps on an interval or a circle, the main difficulty in their classification in real analytic category was to show the absence of wandering domains, which were developed by many dynamicists [7,28,2,8,40], see the survey of van Strien [39].…”
