Local moduli for plane curve singularities, the dimension of the \(\tau\)-constant stratum. (English) Zbl 0681.14013

The main result of the paper gives a closed formula for the dimension of the set of \(\mu\)-constant deformations with minimal Tjurina-number of the plane curve singularity \(f=x^ p_ 1+x^ q_ 2\).
