为了研究时间尺度上的Birkhoff系统动力学,该文给出了时间尺度上delta-nabla导数下Birkhoff系统的运动积分方程.该方程是在一定边界条件和自然边界条件下分别进行研究的.时间尺度上delta导数下、nabla导数下Birkhoff系统的运动积分方程均为该方程的特例.对其它若干特例进行了讨论分析.举例说明了结果的应用.
In order to study Birkhoff dynamics on time scales, the integral equations of motion with delta-nabla derivatives on time scales are presented. Those equations are studied under some boundary conditions and natural boundary conditions respectively. The integral equations of motion with delta or nabla derivatives on time scales are particular cases in this paper. Some other special cases of the results are discussed. An example is given to illustrate the application of the results.
