T. Cardinali et al., AN EXISTENCE THEOREM FOR EVOLUTION INCLUSIONS INVOLVING OPPOSITE MONOTONICITIES, Journal of mathematical analysis and applications, 222(1), 1998, pp. 1-14
In this paper we examine evolution inclusions of the subdifferential t
ype with the set-valued perturbation being nonconvex valued and dissip
ative. Under certain generally mild hypotheses on the data, we prove t
he existence of a strong global solution, extending earlier analogous
results by M. Otani and A. Cellina-V. Staicu. An example of a distribu
ted parameter system is also presented in detail. (C) 1998 Academic Pr
