Geometric properties of the set of Banach limits
E. M. Semenov, F. A. Sukocheva, A. S. Usacheva a University of New South Wales
Abstract:
We study the geometry and extreme points of the set $\mathfrak B\subset l_\infty^*$
of all positive normalized shift-invariant functionals on the space $l_\infty$
of all bounded sequences with the uniform norm. In particular, we calculate the
radius of $\mathfrak B$ and, for a large class of sequences $x$, describe
the orbit of $x$ under the extreme points of $\mathfrak B$.
Keywords:
Banach limit, extreme point, almost convergent sequence.
