摘要: We show how to compute all fundamental numbers for plane cuspidal cubics. This updates and extends the work of Schubert on this subject. In our approach we need a far more precise description first order degenerations (13 in all) than that given by is obtained proving number key geometric relations are satisfied Moreover, procedure does not require using coincidence formulas derive basic degeneration relations.
