Abstract
We find conditions such that every \(\lambda \)-homogeneous model with small \( \lambda \) satisfying these conditions is homogeneous. As a corollary, we obtain conditions guaranteeing that the following implication holds: If \(T \) is a theory, \(\mu >|T| \), and every model of \(T \) of cardinality \( \mu \) is \(\omega _1\) -homogeneous then every model of \(T\) of sufficiently large cardinality is homogeneous.

高同质性和低同质性
摘要
我们发现条件使得每个\(\拉姆达\) -homogeneous小模型\(\拉姆达\)满足这些条件是均匀的。作为推论,我们获得低保下列蕴涵保持条件:如果\(T \)是一种理论,\(\亩> | T | \) ,和每一个模型\(T \)基数的\(\亩\)是\(\ omega _1 \)- 同质的,因此具有足够大基数的\(T \)的每个模型都是同质的。
