Abstract: |
In this article, we study the problems of about ω-very convex spaces and ω-very smooth spaces. Using the local reflexive principle and the slice of unit sphere, we show that the ω-very convex spaces and ω-very smooth spaces are dual notions and study the relation between ω-very convexity, ω-very smoothness with various convexity and smoothness, and give some characteristic descriptions of ω-very smoothness and ω-very convexity . These results perfect the research on convexity and smoothness about Banach spaces. |
Key words: ω-very convexity ω-very smoothness slice |
