N2 - Abstract: We consider a continuous approximation to the Sturm–Liouville problem witha nonlinearity discontinuous in the phase variable. The approximating problem is obtained fromthe original one by small perturbations of the spectral parameter and by approximating thenonlinearity by Carathéodory functions. The variational method is used to prove thetheorem on the proximity of solutions of the approximating and original problems. The resultingtheorem is applied to the one-dimensional Gol’dshtik and Lavrent’ev models of separated flows.
