Here we examine direct reciprocity in structured populations, where individuals occupy the vertices of a graph. The edges denote who interacts with whom. The graph represents spatial structure or a social network. For birth-death or pairwise comparison up...

Yet humans and other animals often interact repeatedly within groups, thereby violating the fundamental basis of these models. W...
