Kamenev-type oscillation criteria for forced Emden-Fowler superlinear difference equations

Samir H. Saker

Using Riccati transformation techniques, we establish oscillation criteria for forced second-order Emden-Fowler superlinear difference equations. Our criteria are discrete analogues of the criteria used for differential equations by Kamanev [5].
