Add to ORKGWe study several classes of nonlinear boundary value problems. We establish existence, uniqueness, multiplicity or bifurcation results. Our analysis relies on the maximum principle or on the critical point theory in the sense of Clarke.On étudie plusieurs problèmes aux limites non linéaires. On établit des résultats d'existence, d'unicité, de multiplicité ou de bifurcation. Notre analyse porte sur le principe du maximum et la théorie du point critique dans le sens de Clarke
