However, in higher dimensions, it turned out that it was easier to find the extrema of . than solve .(.)?=?0. This led to the approach of solving equations of the form .(.)?=?0 by finding extrema of ..

Sandwich Systems,ir does not separate the functional, nothing can be said concerning a potential critical point. This raises the questions, “Is there anything one can do if one cannot find linking sets that separate the functional?” “Are there sets that can lead to critical sequences even though they do not separate
