Projection Constants of a Class of Codimension-2 Subspaces in l∞2 n

Relative projection constants and strong unicity constants for a certain class of projection operators on the space l ∞ 2 n are found. The maximum values of strong unicity constants are calculated for the projection operators with unit norm on certain codimension-2 subspaces formed by using hyperpla...

Description
Summary:Relative projection constants and strong unicity constants for a certain class of projection operators on the space l ∞ 2 n are found. The maximum values of strong unicity constants are calculated for the projection operators with unit norm on certain codimension-2 subspaces formed by using hyperplanes in l ∞ 2 n .
