Abstract

In this paper the concept of l-occurrences of patterns is introduced. Given a word w∈Σ*, we say that w contains a l-occurrence of a pattern p∈E* iff there exists a morphism h : E*→Σ* such that h(p) is a factor of w and |h(a)|≥l for all a∈Σ.

We prove that a pattern p is avoidable iff there exists an infinite binary word that contains no l-occurrence of p for some l.
