Abstract
A new upper and lower solution theory is presented for the second order problem (G'(y))' + f(t, y) = 0 on finite and infinite intervals. The theory on finite intervals is based on a LerayâSchauder alternative, whereas the theory on infinite intervals is based on results on the finite interval and a diagonalization process.
