I. Hlavacek, A NOTE ON THE NEUMANN PROBLEM FOR A QUASI-LINEAR ELLIPTIC PROBLEM OF A NONMONOTONE TYPE, Journal of mathematical analysis and applications, 211(1), 1997, pp. 365-369
The existence and uniqueness of a weak solution of a Neumann problem i
s discussed for a second-order quasilinear elliptic equation in a dive
rgence form. The note is a continuation of a recent paper, where mixed
boundary value problems were considered, which guaranteed the coerciv
eness of the problem. (C) 1997 Academic Press.
