Roughly speaking, we construct an equivalent renorming with the requested properties for every Banach space X where the set NA(X) for the original norm is not \too large". The construction can be applied to every Banach space containing c0 and having a countable system of norming functionals, in particular, to separable Banach spaces containing c0. We also provide some geometric properties of the norms we have constructed.}, title = {Equivalent norms with an extremely nonlineable set of norm attaining functionals}, author = {López Pérez, Ginés and Kadets, Vladimir and Martín Suárez, Miguel and Werner, Dirk}, }
