我们建立了代数簇上多项式方法的精确形式。这些包括一个分割定理,估计家庭的多项式消失在特定的集合和界限的数量连接组件的真实的代数簇。作为第一个应用程序,我们提供了一个一般的发病率估计,是紧在其依赖的大小,程度和尺寸的品种。
We establish sharp forms of the polynomial method over algebraic varieties. These include a partitioning theorem, estimates for families of polynomials vanishing on specific sets and bounds for the number of connected components of real algebraic varieties. As a first application, we provide a general incidence estimate that is tight in its dependence on the size, degree and dimension of the varieties involved.
