Abstract: | For a closed connected triangulatedn-manifoldM, we study some numerical invariants (namedcategory andcovering numbers) ofM which are strictly related to the topological structure ofM. We complete the classical results of 3-manifold topology and then we prove some characterization theorems in higher dimensions.
Finally some applications are given about the minimal number of critical points (resp. values) of Morse functions defined
on a closed connected smoothn-manifold.
