%T Regularizing context-free languages by AFL operations : concatenation and Kleene closure
%X We consider the possibility to obtain a regular language by applying a given operation to a context-free language. Properties of the family of context-free languages which can be "regularized'1 by concatenation with a regular set or by Kleene closure are investigated here: size, hierarchies, characterizations, closure, decidability.
