摘要：
We offer sufficient conditions for the oscillation of all solutions of partial difference equations y(m-1,n)+beta(m,n)y(m,n-1)-delta(m,n)y(m,n)+P(m,n,y(m+k,n+l)) =Q(m,n,y(m+k,n+l)) and y(m-1,n)+beta(m,n)y(m,n-1)-delta(m,n)y(m,n) [GRAPHICS] Several examples which dwell upon the importance of our results are also included.
