摘要：
In this paper, generalized inverses are studied by using (one-sided) clean elements. On one hand, the (one-sided) invertibility along an element is characterized by a (one-sided) clean element. As its applications, the existence criteria for Moore-Penrose inverse, group inverse, core inverse and right core inverse are given. On the other hand, two elements being simultaneously (one-sided) invertible along a same element are characterized by a (one-sided) clean element. As its special cases, the characterizations of an element being both Moore-Penrose invertible and group invertible are given.
