Streszczenie
We discuss a strong version of the Dunford–Pettis property, earlier named $(DP^*)$ property, which is shared by both $\ell _1$ and $\ell _\infty .$ It is equivalent to the Dunford–Pettis property plus the fact that every quotient map onto $c_0$ is completely continuous. Other weak sequential continuity results on polynomials and analytic mappings related to the $(DP^*)$ property are shown.
