El. Dozo et Mc. Mariani, SOLUTIONS TO THE PLATEAU-PROBLEM FOR THE PRESCRIBED MEAN-CURVATURE EQUATION VIA THE MOUNTAIN PASS LEMMA, Studies in applied mathematics, 96(3), 1996, pp. 351-358
Assuming that a function g solves the classical Plateau problem for a
disc-type surface, we give conditions on a non zero function H in R(3)
With respect to g to obtain multiple weak solutions to the correspond
ing problem with mean curvature H.
