Abstract
The authors discuss necessary and sufficient conditions for the existence and uniqueness of slowly oscillating solutions for the differential equation
u'+F(u)=h(t) with strictly monotone operator. Particularly, the authors give necessary and sufficient conditions for the existence and uniqueness of slowly oscillating solutions for the differential equation u'+∇Φ(u)=h(t), where ∇Φ denotes the gradient of the convex function Φ on ℝN.
