   Format: MarkdownItexSpeaking of this, I had wanted to get my hands on a proof that the shift transformation on the space of irrationals between 0 and 1, which sends a continued fraction $[a_1, a_2, a_3, \ldots]$ to $[a_2, a_3, \ldots]$, is ergodic with respect to the measure $\frac1{\log 2}\frac{d x}{1 + x}$. Any ideas where to find such a proof? (Might be nice for an article [[ergodic theory]] as well, since this measure space provides archetypal examples of chaotic phenomena, or so I sense.)

   Format: MarkdownItexI think that there is an encyclopaedia of mathematics and applications: dynamical systems (red cover, edit: or this was about operator algebras and dynamical systems? edit: no, it is very abstract one, I just peeked into it) which has large part dedicated to the shift-type dynamical systems. I had it in hands years ago, so I can not say about the particular result, but I would not be surprised to find it there. Edit: I added a link to [[ergodic theory]] to one course page having some canonical references in ergodic theory.

   Format: MarkdownItexadded to _[[ergodic theory]]_ _[this reference](http://www.math.psu.edu/katok_a/pub/KR.pdf)_ which discusses applications of cohomology theory to the subject. This reminded me of David Corfield's search for cohomological notions in "random" contexts, though maybe it's not relevant, I am not sure.
