Let β be a real number with 1 < β < 2. We prove that the language of the β-shift is ∆0 n iff β is a ∆n-real. The special case where n is 1 is the independently inter...

A new algorithm is presented for testing if a regular language is locally threshold testable. The new algorithm is slower than existing algorithms, but its correctness proof is sh...
