We define the interpolative fusion T of a family (Ti)iI of first-order theories over a common reduct T, a notion that generalizes many examples of random or generic structures in the model-theoretic literature. When each Ti is model-complete, T coincides with the model companion of T =iITi. By obtaining sufficient conditions for the existence of T, we develop new tools to show that theories of interest have model companions.

插值融合

我们定义插值融合*一个家庭的(一世)一世一世一阶理论在一个共同的归约上,这个概念概括了模型理论文献中许多随机或通用结构的例子。当每个一世是模型完备的,*与模型伴侣不谋而合 =一世一世一世. 通过获得存在的充分条件*,我们开发了新的工具来证明感兴趣的理论有模型伴侣。
