The authors consider the following problem: (P) Does every renorming of \(l_2\) have the fixed point property? The purpose of this paper is to give an overview of this question and an example of a renorming of \(l_2\) which seems to fall out of the scope of all known sufficient conditions for the fixed point property. The main results of this paper are interesting and nice.
