Abstract: Fix α ∈ (0,1}, and consider a sequence of partitions of the interval, starting with the trivial one, {[0,1]}, and where the (n+1)st partition is obtained by splitting all maximal intervals in the nth into two, in the ratio α : 1-α.
The question posed to Kakutani: does the set of endpoints of the nth partition become uniformly distributed in the limit? We will consider the answer to this question, and some of its generalisations/variations: whether its more dimensions, intervals or randomness, there appears to be no limit to the questions one can ask. Naturally, some are open. This is joint work with Mark Pollicott.
