Abstract

Some annulus oscillation criteria are established for the second order damped elliptic differential equation under quite general assumption that they are based on the information only on a sequence of annuluses of rather than on the whole exterior domain . Our results are extensions of those due to Kong for ordinary differential equations. In particular, the results obtained here can be applied to the extreme case such as .
