【摘要】 研究了一类中立型非线性抛物方程非振动解的渐近性质，利用在一定条件下将方程的强迫项目并入首项（ｕｔ项）的方法，得到了在混合边值条件下方程的所有非振动解渐近收敛于零的充分条件。更多还原

【Abstract】 Asymptotic property of the nonoscillatary solutions of a class of nonlinear parabolic differential equations of neutral type is discussed. Under the given conditions, the forced term of the parabolic equation is incorporated into its first term (term ut). Sufficient conditions are obtained for asymptotic convergence to Zero of all nonoscillatary solutions of the equations in various boundary conditions.更多还原
