Linearized Oscillation Theory for a Nonlinear Nonautonomous Difference Equation

2020
We review some theorems and mistakes in linearized oscillation results for difference equations with variable coefficients and constant delays, as well as develop linearized oscillation theory when delays are also variable. Main statements are applied to discrete models of population dynamics.

Weighted Averaging Techniques in Oscillation Theory for Second Order Difference Equations

Canadian Mathematical Bulletin, 1992
AbstractWe consider the self-adjoint second-order scalar difference equation (1) Δ(rnΔxn) +pnXn+1 = 0 and the matrix system (2) Δ(RnΔXn) + PnXn+1 = 0, where are seQuences of real numbers (d x d Hermitian matrices) with rn > 0(Rn > 0). The oscillation and nonoscillation criteria for solutions of (1) and (2), obtained in [3, 4, 10], are extended ...

Asymptotic estimate of solution of one mixed difference-differential equation of oscillations theory

Journal of Difference Equations and Applications, 1998
Asymptotic expression of unimprobable estimates of solution of the problem are obtained s is a fixed dyadicN → ∞. Here m, c are positive constants, and is a symmetric difference operator with respect to j. This problem defines tension forces in the homogeneous chain of N material particles, jointed in consecutive order with massless springs of linear ...
