Open Problems in Symbolic Dynamics

This is a website devoted to presenting open problems in symbolic dynamics and tracking their solutions. I welcome suggestions for open problems, links to related problem sites and announcements of solved problems. The initial seed for the site is the survey
Open problems in symbolic dynamics (" OPSD"), from "Geometric and probabilistic structures in dynamics, 69--118, Contemp. Math., 469, Amer. Math. Soc., Providence, RI, 2008."

I'll post announcements of solutions to problems from OPSD, and I hope that those who solve problems from OPSD will include OPSD in their references, so that future workers can easily find solutions in MathSciNet by tracking citations.

Problems from OPSD which have been solved:

• Questions 11.3 and 11.4 were answered in the affirmative by Mike Hochman in "Expansive directions of Z^2 actions" .
