In this paper, we mainly obtained following three theorems on σ-para Lindel?f spaces: (1) If X is a σ-paralindel?f P-space and Y is a σ-expandable strong Σ-space, then X×Y is σ-para Lindel?f space. (2) If X is a σ-paralindelf P*-space and Y has a σ-locally finite base, then X×Y is σ-para Lindel?f. (3) Let X and Y be σ-paralindel?f spaces with orthobase. If X is regular C scattered, then X×Y is σ-para-Lindel?f . |
