【摘要】 通过Riccati变换,讨论了二阶时标非线性动力系统(R(t)xΔ(t))Δ+Q(t)F(x(t))=0,t∈T,的一些新的振动准则,得出了系统振动的几个充分条件;并在文末举例说明了得到的结论是对原有结果的推广。更多还原

【Abstract】 By means of Riccati trans formation techniques, this paper discusses and establishes the oscillation criteria for the second order nonlinear dynamic equations (R(t)x~Δ(t))~Δ+Q(t)F(x(t))=0,t∈T. Meanwhile a nontrivial example is given to illustrate the ctiteria.更多还原
