Uniform integrability and Young measures. (English) Zbl 0930.28004

Summary: We introduce a new property equivalent to uniform integrability. This property, stated in terms of Young measures, seems rather topological. But it appears to be as powerful as other more quantitative properties. Using the same techniques we give a new proof of a theorem of V. Jalby [“Contribution aux problèmes de convergence des fonctions vectorielles et des intégrales fonctionnelles”, Thèse de Doctorat, Montpellier (1993)]. \(\copyright\) Academic Press.
