摘　　要：讨论了拓扑空间的Seq紧性,研究Seq紧空间的刻画及Seq紧子集的性质,并给出序列闭映射的等价刻画和Seq紧映射的定义,进而研究映射与Seq紧性的关系。In this paper, we discuss Seq-compactness in a topological space, study the description of a Seq-compact space and properties of Seq-compact sets, and give the characterizations of sequence-close mappings and the definition of Seq-compact mappings. Furtherly, we study the relationship between mappings and Seq-compactness.
