具有次线性中立项的二阶阻尼微分方程的振动准则

Abstract

Abstract:

In this work, we consider the oscillation of the second order damped differential equation with a sublinear neutral term $(a(t)(z'(t))^{\gamma})'+b(t)(z'(t))^{\gamma}+q(t)x^{\beta}(\sigma(t))=0, $ where $z(t)=x(t)+p(t)x^{\alpha}(\tau(t)) $. By using the generalized Riccati transformation and integral averaging technique, we establish some new oscillation criteria. These results extend and improve some known results. Examples are also provided to illustrate the application of the conclusions.

Key words: Sublinear neutral term, Emden-Fowler equation, Half-linear differential equation, Neutral differential equation, Oscillation
