Abstract

We study the set of periods of the Morse--Smale diffeomorphisms on the nn-dimensional sphere Sn\mathbb{S}^n, on products of two spheres of arbitrary dimension Sm×Sn\mathbb{S}^m \times \mathbb{S}^n with mnm \neq n, on the nn-dimensional complex projective space \mathbb{C}\text{\textbf{P}}^n} and on the nn-dimensional quaternion projective space \mathbb{H}\text{\textbf{P}}^n}. We classify the minimal sets of Lefschetz periods for such Morse--Smale diffeomorphisms. This characterization is done using the induced maps on the homology. The main tool used is the Lefschetz zeta function.
