V-空间和U-空间是两类重要的凸性空间.对V-空间和U-空间进行了推广,引入两类新的k-型凸空间,即k-V-空间和k-U-空间,得到这两类空间的诸多性质.推广了V-凸性模和U-凸性模的概念,并用推广的凸性模概念刻画了k-V-空间和k-U-空间.
V-spaces and U-spaces are important convex spaces.In this paper,we introduce the two new k-type convex spaces as some generalizations of V-spaces and U-spaces.We give the corresponding modulus of these k-type convex spaces,and discuss the relationship between them.In addition,we obtain the some characteristic or properties of these k-type convex spaces.
