摘要 本文研究了可交换范畴理论的结构,得到了如下主要结果:(1)如果T是可交换范畴理论,那么T有一个强极小有限生成系统.(2)如果T(在L中)是可交换范畴理论,那么有一个有限的L0■L使得对所有满足L0■L′■L的L′,T|L′,亦为范畴理论. This paper studies the structure of exchangable and categorical theories and obtains the following main results: (1) If T is exchangable and categorical (over countable or uncountable language), then T has a strongly minimal finitely generating system. (2) If T (in £) is exchangable and categorical, then there is a finite £0 ∈£ such that for all £' with £0∈£'∈£的£',T|£' is also categorical.
