Abstract:This paper is concerned with the partial difference equation Am+1,n+Am,n+1Am,n+pm,nAmk,nl=0,m,n=0,1,2,…,, where k and l are two positive integers, {pm,n} is a real double sequence. Some new oscillation criteria for this equation are obtained.
Keywords:Partial difference equation  Oscillation
