Abstract: We find conditions such that every λ-homogeneousmodel with small λ satisfying these conditions ishomogeneous. As a corollary, we obtain conditions guaranteeing that the following implicationholds: If T is a theory, μ >|T|, and every model of T of cardinality μ is ω1-homogeneous then every model of T of sufficiently largecardinality is homogeneous.
