弱Fraisse范畴

Weak Fraisse categories

Wieslaw Kubiś

摘要:

我们发展了弱Fraisse范畴的理论,其中的关键概念是最近在模型论中发现的弱合并性质。我们证明了在适当的框架下,每个弱Fraisse范畴都有其唯一的极限,即一个更大范畴中的特殊对象,其特征在于内射性的某种变体。这大大扩展了目前的理论弗莱斯限制。

英文摘要:

We develop the theory of weak Fraisse categories, where the crucial concept is the weak amalgamation property, discovered relatively recently in model theory. We show that, in a suitable framework, every weak Fraisse category has its unique limit, a special object in a bigger category, characterized by certain variant of injectivity. This significantly extends the present theory of Fraisse limits.
