On Characteristic Classes Of Determinantal Cremona Transformations
Gerard Gonzalez-Sprinberg, Ivan Pan
We compute the multidegrees and the Segre numbers of general determinantal Cremona transformations, with generically reduced base scheme, by specializing to the standard Cremona tr…

Analytical invariants of quasi-ordinary hypersurface singularities associated to divisorial valuations
Pedro Daniel Gonzalez Perez, Gerard Gonzalez-Sprinberg
We study an analytically irreducible algebroid germ (X, 0) of complex singularity by considering the filtrations of its analytic algebra, and their associated graded rings, induced…
