摘要
对于一类在非牛顿流体力学和多孔介质中的气体湍流等方面有广泛应用的非线性p-La-place微分方程在符号条件和Nagumo条件下周期边值问题解的存在性进行了详细的讨论.在证明过程中利用了迭合度理论及p-Laplace下的“连续性定理”,所得结果推广了Granas和Lee等人已有的结论.
With signal condition and Nagumo condition, the existence of periodic solutions for nonlinear p-Laplaeian differential equation, which is applied extensively in non-Newton fluid and turbulent flow of gas in porous medium, was discussed in detail. In the proof, coincidence degree theory and so called “continuous theorem” under p-Laplacian equation were used and the known results of Granas and Lee＇s were generalized.
