On the context-freeness of the set of words containing overlaps
چکیده انگلیسی

We show that the set of binary words containing overlaps is not unambiguously context-free and that the set of ternary words containing overlaps is not context-free. We also show that the set of binary words that are not subwords of the Thue–Morse word is not unambiguously context-free.
