E. Thandapani et al., OSCILLATION THEOREMS FOR HIGHER-ORDER NONLINEAR DELAY DIFFERENCE-EQUATIONS, Computers & mathematics with applications, 32(3), 1996, pp. 111-117
Some new oscillation results for difference equations of the form (1.1
), and forced difference equations of the form (1.2), are established.
The results obtained are discrete analogues of some known results for
delay differential equations.
