— We characterize space complexity classes in terms of bounded erasing homomorphisms applied to threefoid intersections of one-counter languages, and also we characterize the classes which are given by bounded erasing homomorphisms applied to mixed intersections of one-counter languages and context-free languages or one-counter languages and checking stack languages. A generalization to erasing...
