## Abstract in another language

Quite some time ago, at the singularity conference at Cargèse 1972, Brieskorn asked the following question: "Is the local fundamental group π_1^s(S-D) of the discriminant complement inside the semi-universal unfolding S of an isolated hypersurface singularity constant for s in the μ-constant stratum Σ_E?" We review this question and give an affirmative answer in case of singular plane curve germs of multiplicity at most 3.
