Zhang, Guang; Cheng, Sui Sun A necessary and sufficient oscillation condition for the discrete Euler equation. (English) Zbl 0960.39005 Panam. Math. J. 9, No. 4, 29-34 (1999). Summary: We show that \(\gamma> 1/4\) is the necessary and sufficient condition for every solution of the discrete Euler equation \(\Delta^2 x_{n-1}+\gamma n^{-2} x_n= 0\) to be oscillatory.
