摘要
考虑一类具非线性扩散系数的偶数阶中立型阻尼偏微分方程,通过利用广义Riccati变换和引入参数函数,获得了该类方程在Robin边值条件下解振动的充分条件.
In this paper,A class of even order neutral damped partial differential equation with Nonlinear Diffusion Coefficient is considered,Sufficient condition for each solution to be oscillation is obtained by making use of the generalized Riccati transformation and introducing parameter function under Robin boundary condition.
