Constrained extremal points of a potential can be represented as saddle points of a Lagrangian. We prove existence of such saddle points for nonquadratic potentials in Banach spaces under nonlinear constraints. We then apply these results to the so-called mixed formulation of nonlinear elliptic partial differential equations. [ABSTRACT FROM AUTHOR] |
