Strictly contractive projections on classical sequence spaces
Projections, skewness and related constants in real normed spaces.
Some Remarks On The Fixed Point Stability For Nonexpansive Mappings
Diametrically contractive maps and fixed points.
A Note on Remotal Sets in Banach Spaces
Extensions of linear operators from hyperplanes of
Let be a hyperplane and let be given. Denote In this paper the problem of calculating of the constant is studied. We present a complete characterization of those for which . Next we consider the case . Finally some computer examples will be presented.
