I. Hlavacek et al., ON GALERKIN APPROXIMATIONS OF A QUASI-LINEAR NONPOTENTIAL ELLIPTIC PROBLEM OF A NONMONOTONE TYPE, Journal of mathematical analysis and applications, 184(1), 1994, pp. 168-189
We prove the convergence of Galerkin approximations for a second-order
quasilinear elliptic problem of a divergence form with nonlinear mixe
d boundary conditions. The existence and uniqueness of a weak and appr
oximate solution is studied as well. (C) 1994 Academic Press, Inc.
