每个模都是内射模的逆极限

Every module is an inverse limit of injective modules

George M. Bergman

摘要:

证明了环R上的任意左模A都可以表示为一个内射模的内射子模的向下系统的交,等价地表示为内射的一对一同态的逆极限.如果R是左诺特式的,则A也可以写为内射的满同态系统的逆极限。提出了一些问题。

英文摘要:

It is shown that any left module A over a ring R can be written as the intersection of a downward directed system of injective submodules of an injective module; equivalently, as an inverse limit of one-to-one homomorphisms of injectives. If R is left Noetherian, A can also be written as the inverse limit of a system of surjective homomorphisms of injectives. Some questions are raised.
