摘要
研究一类具有变系数的微分方程,建立了该方程解的振动条件,并给出了方程的线性化极限振动准则.
A class of first order nonlinear neutral equations with variable coefficients and variable delays are discussed. Sharp conditions are established for all solutions of the equations to be oscillatory. Linearized oscillation rules of the equations are also given.
