Existence results for second-order impulsive functional differential inclusions.
Existence theorem for functional-differential contingent equations
Existence theory for functional initial value problems of ordinary differential equations.
Extremal Solutions for a Class of Functional Differential Equations
We study, in Carathéodory assumptions, existence, continuation and continuous dependence of extremal solutions for an abstract and rather general class of hereditary differential equations. By some examples we prove that, unlike the nonfunctional case, solved Cauchy problems for hereditary differential equations may not have local extremal solutions.
