  • Summary

    Value is a generalization of diversity. In ecological terms, it allows measurement of a community when its species are assigned a worth that need not be related to how distinctive they are. Mathematically, the characterization theorem for value measures that we prove here allows us to prove a characterization theorem for the Hill numbers (hence, in principle, the Rényi entropies).
