This is an announcement for the paper "Quantitative Dunford-Pettis property" by Miroslav Kacena, Ondrej F.K. Kalenda and Jiri Spurny. Abstract: We investigate possible quantifications of the Dunford-Pettis property. We show, in particular, that the Dunford-Pettis property is automatically quantitative in a sense. Further, there are two incomparable mutually dual stronger versions of a quantitative Dunford-Pettis property. We investigate their relationship with a quantitative Schur property and prove that $L^1$ spaces and $C(K)$ spaces posses both of them. We also show that several natural measures of weak non-compactness are equal in $L^1$ spaces.
