ABSTRACT
Sequence space and function space are two important spaces. In this paper, we will discuss the properties of the two spaces, for examples, separability, completeness, reflexivity and their conjugate spaces.
Keywords: Sequence space，function space，separability, completeness, reflexivity，conjugate spaces
