In theorem 3. 3. 5, the derivative of lyapunov function along trajectories of system ( 1 ) does n ' t need to be required to be negative definite, which is different from functional differential systems
在定理3 3石中， lyapunov函數沿系統）的解軌線的導數在iezumikhin型條件下不再局限於常負，這一點不同於泛函微分系統 -
The decreasing character of a function with negative derivative can be proved by an analogous argument.
負導數函數具有遞減性的證明完全類似。 -
In the first part of the thesis, we study two one - dimensional dynamical systems with negative schwarzian derivative. by using the non - existence of attractive periodic orbits and wandering intervals, a theorem is obtained that the forward invariant compact sets of the two dynamical systems are uniform hyperbolic
本文第一部分主要考慮兩類具有負schwarz導數的單峰映射的動力學性質，利用吸引周期軌道和游蕩區間的不存在性等，證明了其正向不變緊集的一致雙曲性。 -
In this dissertation, we study some stability properties for two impulsive differential systems employing lyapunov ' s second method : one system is impulsive hybrid differential system : the other is differertial system with impulses at variable time : herein these stability results do not require a lyapunov function to have a negative definite first derivative along trajectories of the system, further we may not require its derivative to restrict the function increasing growth ; and we do not give conditions on continuous portion or discrete portion of the systems respective ! } ", hence we can give mixing conditions on them
在這篇碩士學位論文中，我們主要藉助lyapunov第二方法的思想，討論了兩類脈沖微分系統：脈沖混合微分系統和具有依賴于狀態脈沖的微分系統的穩定性問題。不同於以往的研究，本文所找的lyapunov函數沿系統軌線的一階導數不再局限於常負或定負，甚至不用其導數來限制其增長速度；不再局限於對離散或連續部分分別設置條件，而是對其離散和連續部分設置混合條件。
