%X Every population game defines a vector field on the set of strategy distributions X. The
projection dynamic maps each population game to a new vector field: namely, the one closest
to the payoff vector field among those that never point outward from X. We investigate the
geometric underpinnings of the projection dynamic, describe its basic game-theoretic properties,
and establish a number of close connections between the projection dynamic and the replicator
dynamic.
