Every real Banach space can be renormed to satisfy the denseness of numerical radius attaining operators (Q1261892)

First we show that every Banach space satisfying a certain property, called \(\beta\) (used by Lindenstrauss and Partington) verifies the denseness of the numerical radius attaining operators. Using this result and a renorming theorem by Partington we conclude that every Banach space is isomorphic to a new one satisfying the denseness of the numerical radius attaining operators.
