Abstract

We consider forgetting automata, i.e., linear bounded automata which can only use the operations ‘move’, ‘erase’ (rewrite with a blank symbol) and ‘delete’ (remove completely). A classification of the families of languages corresponding to the possible combinations of operations has been given in [1], here we address some of the problems left open. Furthermore the unary case is being investigated.
