明德数学讲堂系列(八)Jacques Peyrière教授——Variations on the IFSs

报告题目: Variations on the IFSs

报告人:Jacques Peyrière教授,法国Paris-Sud大学数学系

报告时间:2019年3月15日周五下午4:00-5:00

报告地点:国学馆114室

报告内容:

Starting from a set of contractions of a complete metric space X, the IFS formalism (Iterated Functions System) is a way to construct a contraction of the space of nonempty compact subsets of X, endowed with the Hausdorff metric. We propose other constructions of such contractions. An example is developed and the structure of the corresponding fixed point partially elucidated. A few problems and conjectures, supported by formal computations, are listed.
