This paper is concerned with the problem [GRAPHICS] where Omega is a b
ounded domain in R(n) with n greater than or equal to 3 and a(x) is a
nonnegative function in Omega. We give some conditions on the function
a(x), sufficient to guarantee the existence and multiplicity of solut
ions for the considered problem without any assumption on the shape of
Omega.
