For those who wish to read and know more about the lecture I append the following lines (including an extended set of references):

The fractals are not subsets of general topological spaces, but compact subsets of complete
metric spaces. Recall: if (X,d) is a metric space, and if T(d) is the topology induced by
the metric (or distance) d, we get the topological space (X, T(d)) --- on which we defindoIe certain
so-called Hausdorff measures. Thus the title of the lecture could be extended by the word "Measure" resulting in the title of Gerald Edgar´s book (1).
However, I don´t need to develop the measure thing in the lecture as fully as Edgar.

A novelty of the lecture is the consideration of measures on the Borel sets Bo(T) for quite
general non-metrizable spaces (X,T) some of these being my own invention. The use and utility of this approach for Fractal Geometry is an objective of further exploration.

Fractal Geometry is also a visual art. In this respect I recommend especially the two books of Barnsley (2) and (3). And the book (6) of Patty is currently the best and most comprehensive
introduction to topology I know of.

The prerequisites to understand the lecture are very few since everything will be explained
from scratch.

The first session will be held October 17, 14:15 - 15:30 in room 00.133-128 ("Animationslabor").
