报告摘要：

    Berestycki et al.[JMB., 66, p743-766] established a Field-Road model, which could describe the spread of invasive species on a large field with a relatively narrow road. There were many interesting results about this model, but we are not aware of any rigorous derivation for their model. In this talk, we aim to seek a rigorous derivation of this model by the effective boundary condition method. Firstly, we start from a well defined problem, called full model, on a large field with a width δ>0 road, and then give some energy estimates. Finally we can derive the Field-Road model by sending δ→0. Moreover, we also derive a dynamic boundary condition (also Wentzell type condition) model from another full model with different transmission condition in a similar way.
