| 摘 要： | 该文讨论了一类在量子理论中有着较多应用的具耗散项的非线性Hartree方程。分别从耗散系数和初值两个方面讨论了解的整体存在性条件。一方面,利用Strichartz估计,得到仅依赖于耗散系数的整体存在性条件。另一方面,也得到了仅依赖于初值大小的整体存在性条件。而且,还得到了一个整体解存在的小初值准则。

| Abstract: | This paper is concerned with the weakly damped nonlinear Hartree equation which has many interesting applications in quantum theory. We discuss the global existence of this equation from two aspects, the damped coefficients and theinitial data, respectively. By Strichartz estimate, we obtain a global existence result which depends on the size of the damped parameter. We also get the other global existence result depending on the initial data. Moreover, a small initial data criterion of global existence is obtained. |
