We consider solutions of semilinear equations on domains of the model spaces of constant curvature
S^2, R^2 and H^2. Under suitable conditions on the domain, we prove uniqueness and non-degeneracy of the critical point. Roughly speaking, a bit less than convexity is required for spherical domains, a bit more for hyperbolic domains. We will also discuss optimality of the conditions. Based on joint works with F. Gladiali and M. Grossi
