Oscillation criteria for second order difference equation

Funkcialaj Ekvacioj, 1991
Consider the difference equation \(\Delta^ 2x_{k-1}+b_ kx_ k=0\), \(k\geq 1\), where \(\Delta x_ k=x_{k+1}-x_ k\) and \(b_ k\geq 0\) with infinitely many positive terms. This equation is said to be oscillatory if it admits a solution \(\{x_ k\}^ \infty_ 0\) with the property that for any \(N\geq 1\), there exists an \(n\geq N\), such that \(x_ kx_{k+1}\

Oscillation criteria for difference equations with damping terms

Applied Mathematics and Computation, 2004
The authors study the oscillation of second order nonlinear difference equations with damping of the form \[ \Delta(a_n(\Delta x_n)^\gamma)+p_n(\Delta x_n)^\gamma+q_nf(x_{n+1})=0, n=n_0,n_0+1, \cdots. \tag{1} \] By means of generalized Riccati transformation techniques, several new oscillation criteria are established for oscillation of all solutions ...

Oscillation Criteria for Semilinear Equations in General Domains

Canadian Mathematical Bulletin, 1976
Oscillation theory for nonlinear ordinary differential equations has been extensively developed in recent years by several authors. We refer the reader to the recent paper by Noussair and Swanson, [2], where an extensive bibliography may be found. The situation is somewhat different for the case of second order partial differential equations, an area ...
