Abstract

Abstract:

By using average functions and integral operators, some domain oscillation criteria for second order demped elliptic equations are tablished,which are different from most known ones in the sens e that they are based on the information only on a sequence of subdomians of Ω(1), rather than on the whole of Ω(1).

Key words: Domain oscillation; , Second order demped elliptic equat ions, Averaging function, Integral operator.
