Query: Torus actions on rationally elliptic manifolds   An upper bound is obtained on the rank of a torus which can act smoothly and
effectively on a smooth, closed, simply connected, rationally elliptic
manifold. In the maximal-rank case, the manifolds admitting such actions are
classified up to equivariant rational homotopy type.
