On signale une lacune dans la preuve de l’existence d’un homomorphisme régulier universel pour les cycles de codimension 2 sur une variété projective lisse par Murre, et on donne deux arguments différents pour combler cette lacune.

We point out a gap in Murre’s proof of the existence of a universal regular homomorphism for codimension 2 cycles on a smooth projective variety, and offer two arguments to fill this gap.
