Analytical invariants of quasi-ordinary hypersurface singularities associated to divisorial valuations

We study an analytically irreducible algebroid germ ðX ; 0Þ of complex singularity by considering the filtrations of its analytic algebra, and their associated graded rings, induced by the divisorial valuations associated to the irreducible components of the exceptional divisor of the normalized blow-up of the normalization ðX ; 0Þ of ðX ; 0Þ, centered at… CONTINUE READING
