摘要：
We study the oscillatory properties of the solutions of the third-order nonlinear semi-noncanonical delay difference equation D3y(n) + f(n)y(beta)(sigma(n)) = 0, where D(3)y(n) = Delta(b(n)Delta(a(n)(Delta y(n))(alpha))) is studied. The main idea is to transform the semi-noncanonical operator into canonical form. Then we obtain new oscillation theorems for the studied equation. Examples are provided to illustrate the importance of the main results.
