                | The notion of compactness, which is an important content in functional analysis, is widely used in modern analytical science. In this article, the compactness of set is discussed in lp,p≥2. It is proved that Mlp is pre compact set in lp if and only if M is uniformly bounded and uniformly convergent. As an application, an example is presented here. |
