Spectrum and V-Filtration - Variance of Spectral numbers

Claus Hertling conjectures that

variance(SN) <= (SN_max - SN_min) / 12 .

We compute

g(f) := mu(f) * ((SN_max - SN_min) - 12*variance(SN)) .

for semiquasihomogeneous singularities.

for Newton nondegenerate singularities.

for Newton degenerate singularities.
