Xing Hu, Yongkun Li

摘要:

首先证明了时间尺度上Riemann-Liouville分数次积分的两种定义的等价性,然后利用Riemann-Liouville在时间尺度上的分数次导数的概念,引入分数索伯列夫空间,刻画了它们的特征,定义了弱分数次导数,并证明了它们与时间尺度上的Riemann-Liouville分数次导数是一致的。其次,我们证明了一些范数在引入的空间中的等价性,并得到了它们的完备性、自反性、可分性和一些嵌入。最后,作为应用,通过构造适当的变分设置,利用山路定理和亏格性质,研究了一类具有边界条件的时间尺度上Kirchhoff型分数p-Laplacian方程组弱解的存在性,得到了该问题弱解存在性的三个结果.

英文摘要:

We first prove the equivalence of two definitions of Riemann-Liouville fractional integral on time scales, then by the concept of fractional derivative of Riemann-Liouville on time scales, we introduce fractional Sobolev spaces, characterize them, define weak fractional derivatives, and show that they coincide with the Riemann-Liouville ones on time scales. Next, we prove equivalence of some norms in the introduced spaces and derive their completeness, reflexivity, separability and some imbeddings. Finally, as an application, by constructing an appropriate variational setting, using the mountain pass theorem and the genus properties, the existence of weak solutions for a class of Kirchhoff-type fractional p-Laplacian systems on time scales with boundary condition is studied, and three results of the existence of weak solutions for this problem is obtained.
