Monotonicity and upper semicontinuity
1976
Bulletin of the American Mathematical Society
Introduction. We show in this note that set valued maximal monotone operators on a Hilbert space possess the upper semicontinuity property called property (0, introduced by Cesari [2] and used extensively in the existence analysis of optimal control theory. As a particular consequence we conclude rather easily, the known result (see [1] , for example) that maximal monotone operators have closed graph and are thus demiclosed. As a simple application of this to optimal control theory we give an
