We study boundary value problems for systems of second-order ordinary differential equations with quasimonotonicity conditions typical of problems of activator–inhibitor type and with solutions containing domains with large gradients. We obtain sufficient conditions for the existence of a stable stationary solution. Using the asymptotic method of differential inequalities, we prove the existence and stability theorems.
Keywords: internal transition layer, method of differential inequalities, upper and lower solutions, asymptotic approximation, quasimonotonicity conditions.
