Some new fixed point theorems are presented for operators of accretive, nonlinear contractive, or nonexpansive type. These results are then used to establish a new existence principle for second order boundary value problems in Hilbert spaces.

In this paper, a class of mixed monotone operators with convexity and concavity are investigated, and existence and uniqueness theorems of fixed points are obtained. Moreover, some applications to nonlinear integral equations on unbounded regions and differential equations in Banach spaces are given
A b s t r a c t --I n this paper, some fixed-point theorems for discontinuous multivalued operators on ordered spaces are proved. These theorems improve the earlier known fixed-point theorems of [1,2]. The main fixed-point theorems are applied to first-order discontinuous differential inclusions for
