摘要
我们从盖夫曼分裂定理的角度研究了 PA - $\mathsf {PA}^-$ 上各种集合方案的模型论特征。其中,我们证明了对于任意 n ≥ 0 $n \ge 0$ 和 M ⊧ PA - $M \models \mathsf {PA}^-$ ,以下内容是等价的:
On collection schemes and Gaifman's splitting theorem
We study model theoretic characterizations of various collection schemes over from the viewpoint of Gaifman's splitting theorem. Among other things, we prove that for any and , the following are equivalent:
