We construct a countable family of open intervals contained in (0,1] whose endpoints are quadratic surds and such that their union is a full measure set.

Abstract
We construct a countable family of open intervals contained in (0,1] whose endpoints are quadratic surds and such that their union is a full measure set. We then show that these intervals are precisely the monotonicity intervals of the entropy of α-continued fractions, thus proving a conjecture of Nakada and Natsui.File in questo prodotto:
