A MAXIMUM PRINCIPLE FOR SOLUTIONS OF A CLASS OF QUASILINEAR ELLIPTIC EQUATIONS ON UNBOUNDED DOMAINS
Zhiren Jin, Kirk Eugene Lancaster · Communications in Partial Differential Equations · 2002
For solutions on unbounded domains of boundary value problems for a class of quasilinear elliptic equations which are not uniformly elliptic, we prove that the solutions have the same bounds as those of the boundary data.
