A symmetric basis of the algebra of quasi-symmetric coinvariants
The electronic journal of combinatorics, Tome 12 (2005)
On décrit une nouvelle base de l'algèbre des coinvariants quasi-symétriques, qui est stable par l'involution naturelle et indexée par les triangulations d'un polygone régulier. [We describe a new basis of the ring of quasi-symmetric coinvariants, which is stable by the natural reversal of the set of variables. The indexing set is the set of triangulations of a regular polygon, instead of the set of Dyck paths used for the known basis.]
