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.
