Abstract and Applied Analysis, 2003, vol. 2003, 1-7

Abstract:

We give an example of an unbounded, convex, and closed set C in the Hilbert space l 2 with the following two properties: (i) C has the approximate fixed-point property for nonexpansive mappings, (ii) C is not contained in a block for every orthogonal basis in l 2 .
