On the number of sets definable by polynomials
We show that the known algorithms used to re-write any first order quantifier-free formula over an algebraically closed field into its normal disjunctive form are essentially optimal. This result follows from an estimate of the number of sets definable by equalities and inequalities of fixed polynom...

| Sumario: | We show that the known algorithms used to re-write any first order quantifier-free formula over an algebraically closed field into its normal disjunctive form are essentially optimal. This result follows from an estimate of the number of sets definable by equalities and inequalities of fixed polynomials. Finally we apply our results to obtain similar estimates in the real case. © 2000 Academic Press. |
