Neste artigo, estudamos palavras d-primitivas e palavras concatenadas D(1). Primeiro mostramos que nem D(1), o conjunto de todas as palavras d-primitivas, nem D(1)D(1), o conjunto de todos D(1) palavras concatenadas, é regular. A seguir mostramos que para u, v, w ∈Σ+ com |u|=|w|, uvw ∈ D(1) se e somente se uv+w ⊆ D(1). Também é mostrado que toda palavra d-primitiva, com comprimento de dois ou mais, é D(1)-concatenado.

Abstract: In this paper, we study d-primitive words and D(1)-concatenated words. First we show that neither D(1), the set of all d-primitive words, nor D(1)D(1), the set of all D(1)-concatenated words, is regular. Next we show that for u, v, w ∈Σ+ with |u|=|w|, uvw ∈ D(1) if and only if uv+w ⊆ D(1). It is also shown that every d-primitive word, with the length of two or more, is D(1)-concatenated.
