A renorming of ℓ2, rare but with the fixed‐point property
Antonio Jiménez-Melado, Enrique Llorens-Fuster · International Journal of Mathematics and Mathematical Sciences · 2003
We give an example of a renorming of ℓ2 with the fixed‐point property (FPP) for nonexpansive mappings, but which seems to fall out of the scope of all the commonly known sufficient conditions for FPP.
