Abstract
The aim of this paper is to study the symmetry properties of positive solutions of nonlinear elliptic boundary value problems of type Du + f (|x|, u,ru) = 0 in Rn. u(x) ! 0 as |x| ! ¥ We employ the moving plane method based on maximum principle on unbounded domains to obtain the result on symmetry. Keywords: Maximum principle; Moving plane method; Semilinear elliptic boundary value problems.
