论文摘要
针对其细菌宿主免疫系统的噬菌体的某些防御机制依赖于噬菌体的合作。在这个示例中，我们分析了中度结构化的宿主人群中合作寄生虫的入侵概率。更确切地说，我们假设主机是在配置模型的顶点上排列的，并且寄生虫的后代移至最近的邻居站点以感染新的主机。我们认为寄生虫在生殖时会产生许多后代，但是（通常）仅在同时感染宿主时（通常）。在这个制度中，我们识别和分析了寄生虫的入侵从不太可能发生到高度可能的事件的人口结构的空间量表。
Certain defense mechanisms of phages against the immune system of their bacterial host rely on cooperation of phages. Motivated by this example we analyse invasion probabilities of cooperative parasites in host populations that are moderately structured. More precisely we assume that hosts are arranged on the vertices of a configuration model and that offspring of parasites move to nearest neighbours sites to infect new hosts. We consider parasites that generate many offspring at reproduction, but do this (usually) only when infecting a host simultaneously. In this regime we identify and analyse the spatial scale of the population structure at which invasion of parasites turns from being an unlikely to an highly probable event.
