Topic: Information Theory and Fractal Geometry February 3

Presenter: H. Furstenberg, Hebrew University

Abstract: The intersection theory of fractals in Euclidean space is quite different from that of algebraic and differentiable

varieties. Thus one can construct two fractal sets, A and B in R^m each of (full) dimension m, such that every translate of

A meets B in at most one point. However for "good" pairs of fractals the traditional inequality holds: for some translate

A', the codimension of the intersection of A' and B is less than or equal to the sum of the codimensions of A and B. The

proof will use information theory and the ergodic theorem.
