置换空间P_BB_S的某些凸性及(ω)性质

SEVERAL COVEXITIES AND (ω) PROPERTY IN SUBSTITUTION SPACESP_BB_S

讨论了置换空间PBPS的强凸性、非常凸性、近强凸性、极端凸性及(ω)性质,其结果推广了文献[6]等相应的结论.

In this paper, we discusses the strong convexity, very convexity, near strong convexity, extremal convexity and (w) property, and the results generalize the corresponding results in refrence and so on.
