AAYA, Hassan; HILALI, Mohamed Anas; HILALI, Mohamed Rachid  and  JAWAD, Tarik. On the toral rank conjecture and some consequences. Proyecciones (Antofagasta) [online]. 2017, vol.36, n.2, pp.299-306. ISSN 0716-0917.

The aim of this work is to improve the lower bound of the Puppe inequality. His theorem [15,Theorem 1.1] states that the sum of all Betti numbers of a well-behaved space X is at least equal to 2n, where n is rank of an n-torus T n acting almost freely on X.
