论文摘要
我们表明,当且仅当对于每个Prime $ p $时,$ p $ - $ a $的$ p $ - 主要部分是有限的,或者它与prüfer$ p $ - 组相吻合时,且仅当每个prime $ p $,$ p $ - 主要部分是有限的。我们还提供了我们获得的模型伴侣的模型理论描述。
We show that the theory of Galois actions of a torsion Abelian group $A$ is companionable if and only if for each prime $p$, the $p$-primary part of $A$ is either finite or it coincides with the Prüfer $p$-group. We also provide a model-theoretic description of the model companions we obtain.
