Understanding the problem

Read the background

Two reduced weighted-homogeneous complex hypersurface germs with isolated singularities are ambiently homeomorphic but have multiplicities two and three. They lie in one finite complex ambient dimension divisible by eight.

Why it matters

If correct, gives a negative answer to Zariski’s embedded multiplicity conjecture even for isolated hypersurface singularities.

What counts as progress

Does the embedded topology of an isolated complex hypersurface singularity determine its multiplicity?
