In this work is presented some important results about Anosov actions of R k in (k + 2)−closed manifolds. We obtained two classification theorems (Theorems A and B) which give us, essentially, that the system is a T k−1-extension of an Anosov flow. In order to show that, we used the theory of foliations of codimension one, techniques developed by Fenley, such as study of the lift of the action in the universal cover and the construction of invariant lozenges, what is more, we used some results by Maquera and Barbot, who began the studies of Anosov Actions generalizing some classic results on the way to classificate them.
