We are concerned with the oscillatory behavior of the second order elliptic equation

1

where Δ is the Laplace operator in n-dimensional Euclidean space Rn, E is an exterior domain in Rn, and c:E × R → R and f:E → R are continuous functions.

A function v : E − R is called oscillatory in E if v(x) has arbitrarily large zeros, that is, the set {xE : v(x) = 0} is unbounded. For brevity, we say that equation (1) is oscillatory in E if every solution uC2(E) of (1) is oscillatory in E.
