Melkersson子范畴在内射壳下不闭的一个例子
An example of Melkersson subcategory which is not closed under injective hulls
摘要：
Melkersson子范畴是一个特殊的Serre子范畴。证明了在内射壳下闭的Serre子范畴是Melkersson子范畴。然而，这是一个悬而未决的问题是否相反的含义成立。在本文中，我们将表明，这个问题一般有一个否定的答案。
英文摘要：
The Melkersson subcategory is a special Serre subcategory. It was proved that a Serre subcategory which is closed under injective hulls is a Melkersson subcategory. However, it has been an open question whether the contrary implication holds. In this paper, we shall show that this question has a negative answer in general.
