Abstract: A lower and upper solution method is introduced for control problems related to abstract operator equations. The method is illustrated on a control problem for the Lotka-Volterra model with seasonal harvesting and applied to a control problem of cell evolution after bone marrow transplantation.
Keywords: control problem; lower and upper solutions; fixed point; approximation algorithm; numerical solution; medical application.
