Abstract

A version of Fatou's lemma for multifunctions with unbounded values in infinite dimensions is presented. It generalizes both the recent Fatou-type results for Gelfand integrable functions of B. Cornet and V. F. Martins da Rocha ["Fatou's lemma for unbounded Gelfand integrable mappings", preprint 109, CERMSEM, Université Paris I (2002)] and, in the case of finite dimensions, the finite-dimensional version of the unifying multivalued Fatou-type result of E. J. Balder and C. Hess [Math. Oper. Res. 20 (1995) 175–188].
