Място: Зала 578, ИМИ - БАН Заглавие на доклада: The complete intersection discrepancy of curves Докладчик: Andrei Bengus-Lasnier (ИМИ - БАН) Резюме: In this talk I will introduce an invariant for reduced curves called the complete intersection discrepancy (cid for short). This numerical quantity arose naturally when trying to generalize known formulas for complete intersection curves to general curves. The cid then serves as a correction term in these formulas. I will present some of the cid's basic properties and derive two formulas. The first relates basic invariants such as Milnor number, its multiplicity and the multiplicity of its Jacobian ideal, and generalizes a well-known result in singularity theory due to Lê, Greuel and Teissier. The second formula [...]
