  This paper studies a meta-simplex concept and geometric embedding framework
for multi-population replicator dynamics. Central results are two embedding
theorems which constitute a formal reduction of multi-population replicator
dynamics to single-population ones. In conjunction with a robust mathematical
formalism, this provides a toolset for analyzing complex multi-population
models. Our framework provides a unifying perspective on different population
dynamics in the literature which in particular enables to establish a formal
link between multi-population and multi-game dynamics.
