我们证明了一类子集的结构一致定义的一阶公式是一个Vapnik-Chervonenkis类当且仅当该公式不具有独立性。通过这种联系,我们得到了几个新的例子Vapnik-Chervonenkis类,包括集的积极性的subanalytic功能。
We show that a class of subsets of a structure uniformly definable by a first-order formula is a Vapnik-Chervonenkis class if and only if the formula does not have the independence property. Via this connection we obtain several new examples of Vapnik-Chervonenkis classes, including sets of positivity of finitely subanalytic functions.
