RT Journal Article T1 Commutators and commutator subgroups of the Riordan group A1 Luzón, Ana A1 Alonso Morón, Manuel A1 Prieto Martínez, Felipe AB We calculate the derived series of the Riordan group. To do that, we study a nested sequence of its subgroups, herein denoted by Gk. By means of this sequence, we first obtain the n-th commutator subgroup of the Associated subgroup. This fact allows us to get some related results about certain groups of formal power series and to complete the proof of our main goal, Theorem 1 in this paper.
