ONE-SIDED ESTIMATES FOR QUASIMONOTONE SYSTEMS OF BOUNDARY VALUE PROBLEMS
Gerd Herzog · Demonstratio Mathematica · 2004
We prove existence and uniqueness theorems for Dirichlet boundary value problems of the form u" + f{t,u) -0, u(0) = uo, u(l) = ui in ordered finite dimensional Banach spaces, involving one-sided estimates and quasimonotonicity.
