Abstract
I present a generalization of kin-selection theory to interactions involving more than two individuals, using matrix notation. This matrix approach to the analysis of social groups provides some useful summary statistics: an index of the concentration of relatedness within the group and an index of the evenness of relatedness within the group. Further, it can be used to determine the apportionment of benefits that optimizes each individual's inclusive fitness and the strategy that simultaneously optimizes the inclusive fitnesses of all group members. Finally, a method is provided for analyzing the potential for conflict within social groups.
