Abstract

The aim of this paper is to establish a result of which the following is a particular case: If F is a nonempty closed-valued measurable multifunction, from a nonatomic d(0,F( ·)) Î L1 (T) and liml® + ¥ \fracd(lx,F(t))l = 0d(0,F( \cdot )) \in L^1 (T) and \mathop {\lim }\limits_{\lambda \to + \infty } \frac{{d(\lambda x,F(t))}}{\lambda } = 0
for almost every t isin T and for every x isin E, then each closed hyperplane of L 1(T,E) contains a selection of F. Also, some consequences are indicated.
