| Problem: | Determine the strata of constant Tjurina number in the basis of a semiuniversal deformation of the hypersurface singularity given by f |
Let m1,...,mr be a monomial basis of the Tjurina algebra
Tlocal(f) = K[x,y]<x,y>/< jacob(f), f >.
A semiuniversal deformation of f is then given by
F=f+t1m1+...+trmr
The relative T1 of F,
