Abstract
Let X be a connected topological spaces with finite rational Betti numbers. We denote by G the radical of its fundamental group and by (∧V,d) its minimal Sullivan model. If dim Vi<∞ for each i≥2 , then the dimension of the rationalization of G is less than or equal to the Lusternik-Schnirelmann category of X.
