I will discuss the construction of (fractal) sets in metric spaces and
visit the following topics:
(1) Separation conditions for self-similar mappings in metric spaces. In
particular the open set condition and requirements that accompany it.
(2) An approach to study set constructions in metric spaces which, for
example, do not support any non-trivial similitude mappings.
(3) The simple and yet powerful idea of mixing self-similar
constructions. Some examples in Carnot groups will be given.http://cvgmt.sns.it/seminar/11/
