自然界中发生在不同时间地点的多个事件往往都是互相关联的。如2018/2019年冬天美国的严寒和澳大利亚的酷热这样的反常气候是与2018年春夏北冰洋的冰持续偏少紧密相关的。目前没有很好的数学物理模型来描述这些发生在多地的关联事件。我们定义描述发生在不同时间地点的关联事件的模型为多地系统，对应的物理学为多地物理学。项目将侧重于多地系统的建立、多地系统的特性研究、求解及可能的应用。在多地系统的建立方面，侧重于非线性薛定谔型、KdV-KP-Toda型和修正KdV-sG型的二地、四地和三地系统的建立；在多地系统的特性研究方面将侧重于可积性及其与传统的局域系统之间不同的新物理和新数学；在多地系统的求解方面，将侧重于与传统的局域系统不同的求解方法(如将任意函数按非局域相关算子的对称-反对称分解的方法)及解的不同结构；在多地系统的应用方面将侧重于多地系统研究中得到的新物理和新数学是否可能得到新的应用。

Several events occurred at different space-times are often related to each other. Abnormal climates such as the extremely cold in the United States and the extremely hot in Australia in the winter of 2018/2019 are closely related to the continued scarcity of ice in the Arctic Ocean in the spring and summer of 2018. There is currently no good mathematical physical model to describe these correlated events that occur in different places and different times. We define the model that describes the associated events that occur at different space-times as multi-place systems, and the corresponding physics is defined as multi-place physics. The project will focus on the establishment of multi-place systems, the study of the characteristics of multi-place systems, solutions and possible applications. In the establishment of multi-place systems, the emphasis is on the establishment of nonlinear Schrodinger type, KdV-KP-Toda type, and modified KdV-sG type two-, four-, and three-place systems; In the study of the characteristics of multi-place systems, emphasis will be placed on integrability and its different new physics and new mathematics from traditional local systems; In the solution of multi-place systems, different methods (such as the symmetric-antisymmetric decomposition of any function according to non-locality correlated operators) and different structures of solutions will be emphasized. The application of multi-place systems will focus on whether new physics and new mathematics obtained in the study on multi-place systems can be applicable.
