Recursively enumerable (RE) languages are closed under union, intersection, and concatenation, meaning the result of these operations on RE languages is also an RE language. However, they are not closed under complementation, as the complement of an RE language is not necessarily RE. Additionally, RE languages are closed under Kleene star, demonstrating that these languages maintain their classification under these specific operations.
