Abstract

The method of upper and lower solutions is presented for the xed
point problem associated to operators which are compositions of a
linear operator and a nonlinear mapping. Spectral properties of the
linear part together with growth and monotonicity properties of the
nonlinear part are involved. An application to singular boundary value
problems is included.
