The α-Kakutani equidistribution problem, and friends.

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.
