Classification of the extreme points of Ls (2l3∞) by computation

초록

Let l3 infinity = R3 be endowed with the supremum norm. In [Comment. Math. 2017, 57 (1), 1-7], S.G. Kim classified the extreme points of the unit ball of Ls(2l3 infinity) only using Mathematica 8, where Ls(2l3 infinity) is the space of symmetric bilinear forms on l3 infinity. It seems to be interesting and meaningful to classify the extreme points of the unit ball of Ls(2l3 infinity) without using Mathematica 8. The aim of this paper is to make such classification by mathematical calculations.
