| Abstract: | In order to get more images of 2 - sequence - coveting mappings, the concept of double point - star so - covers is introduced. By using ＂ ls - Ponomarev - system＂ which generalizes the Ponomarev methods, this paper obtains that spaces with a double point -star so -cover are closely related to the 2 -sequence -coveting compact images. |
