The conjecture H: A lower bound of cohomologic dimension for an elliptic space
arXiv:0712.3784
Abstract
The goal of this paper is to ameliorate the sufficients conditions, already established by the first author so that the sum of the numbers of Betti, of 1-connected rational finite CW-complex, is higher than the dimension of his -vectorial space of homotopy, we will present it in two aspects, one algebraic and another geometrical.
