Farthest Points and Subdifferential in ๐-Normed Spaces
We study the farthest point mapping in a ๐-normed space ๐ in virtue of subdifferential of ๐(๐ฅ)=sup{โ๐ฅโ๐งโ๐โถ๐งโ๐}, where ๐ is a weakly sequentially compact subset of ๐. We show that the set of all points in ๐ which have farthest point in ๐ contains a dense ๐บ๐ฟ subset of ๐....
