ON THE RATIONAL HOMOTOPY TYPE WHEN THE COHOMOLOGICAL DIMENSION IS 9
An elliptic space is one whose rational homotopy and rational cohomology are both finite dimensional -vector spaces. Our main goal in this paper is to give a full classification of the rational homotopy type for all simply connected and elliptic spaces of cohomological dimension equal to 9.
