Quotient complexity of ideal languages (2009)
Brzozowski, J., Jirásková, G., Li, B.
We study the state complexity of regular operations in the class of ideal languages. A language L over an alphabet Sigma is a right (left) ideal if it satisfies L = L Sigma* (L = Sigma* L). It is a...
Closures in Formal Languages and Kuratowski's Theorem (2009)
