A permutation based approach to the -deformation of the Dynkin Operator
Darij Grinberg, Ekaterina A. Vassilieva
Introduced by Solomon, the descent algebra is a significant subalgebra of the group algebra of the symmetric group related to many important algebraic and combinato…

The enriched -monomial basis of the quasisymmetric functions
Darij Grinberg, Ekaterina A. Vassilieva
We construct a new family of quasisymmetric functions for each element of the base ring. We call them the…

The left-to-right minima basis of the group algebra of the symmetric group (updated version)
Darij Grinberg, Ekaterina A. Vassilieva
We introduce a new basis of the group algebra of the symmetric group, built using the left-to-right minima sets of permutations. We show that on this basis, the descent algebra act…
