论文摘要
在本文中，我们考虑了一个空旷的问题：任何提升模块是否满足有限的内部交换属性？我们为空心和统一模块的平方提出表征，并将上述问题否定为该结果的应用。
In this paper, we consider the open problem: does any lifting module satisfy the finite internal exchange property? We give characterizations for the square of a hollow and uniform module to be lifting, and solve the above problem negatively as an application of this result.
