Explicit models of ${\ell }_1$-preduals and the weak${}^{\ast }$ fixed point property in ${\ell }_1$

Emanuele Casini, Enrico Miglierina, Łukasz Piasecki

We provide a concrete isometric description of all the preduals of ${\ell }_1$ for which the standard basis in ${\ell }_1$ has a finite number of $w^{\ast }$-limit points. Then, we apply this…
