Query: Semi-algebraic sets and equilibria of binary games   Any nonempty, compact, semi-algebraic set in [0, 1] n is the projection of
the set of mixed equilibria of a finite game with 2 actions per player on its
first n coordinates. A similar result follows for sets of equilibrium payoffs.
The proofs are constructive and elementary.
