查询词典 lemma

In this paper, by using the notable Mountain Pass Lemma of critical point theory, some sufficient conditions for the existence and multiplicity of periodic and subharmonic solutions to a class of second order nonlinear functional difference equations with Jacobi operators are obtained.

论文研究了一类具有Jacobi算子类型的二阶非线性泛函差分方程(1)的周期解和次调和解的存在性与多重性。首先将方程（1）的解的存在性问题转化为某个泛函临界点的存在性问题，然后验证此泛函满足著名的山路引理的条件，从而得到论文的主要结论。

When the parameters are unknown, based on the Lyapunov theory, corresponding controller and the adaptive law of parameters are designed to suppress chaos to any unstable equilibrium by the adaptive control strategy. The asymptotical stability of chaos control is guaranteed in theory by lemma of Barbalat.

当该混沌系统的参数未知时，基于Lyapunov稳定性理论，利用自适应控制策略，设计了相应的非线性控制器和参数自适应律将混沌系统的轨道控制到其任意一个平衡点，并借助Barbalat引理，从理论上证明保证了混沌控制的渐近稳定性。
