Here is a nice new page to describe automata theory results.

In class on 27 Feb we mentioned Buchi's Theorem (proved at the link), that a language is regular iff it can be

defined by a formula in second-order monadic logic.

The proof that languages are first-order definable if and only if they are star-free regular is on the Descriptive Complexity page.

The proof that languages are regular if and only if they are recognized by finite monoids is on the Algebra page.
