Abstract
We prove that every monomorphism of the Lie algebra un of triangular derivations of the polynomial algebra Pn=K[x1,…,xn] is an automorphism.
RésuméNous montrons que tout homomorphisme injectif de lʼalgèbre de Lie un des dérivations triangulaires de lʼalgèbre de polynômes Pn=K[x1,…,xn] est un automorphisme.
