摘要
利用自共轭二阶线性差分方程的一些结论,研究了形如Δ2xn+anxγn+1=fn的差分方程的无界解,有界解的存在性及这类解的渐近性质。这类方程可看作Emden-Fowler微分方程的带强迫项的离散形式。
The existence and asymptotic behavior of bounded and unbounded solutions for difference equation Δ~2x_n+a_nx~γ_(n+1)=f_n were obtained.The equation of this type was viewed as perturbation of the second order self adjoint difference equation.
