On the length of cohomology spheres
Denise de Mattos, Edivaldo Lopes dos Santos, Nelson Silva
We present the length, a numerical cohomological index theory, of -spaces which are cohomology spheres and is a -torus or a torus group, where is a prime. As a co…

Some results on extension of maps and applications
C. Biasi, A. Libardi, T. Melo +1
This paper concerns extension of maps using obstruction theory under a non classical viewpoint. It is given a classification of homotopy classes of maps and as an application it is…
