A permutation based approach to the $q$ -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 $k S_{n}$ related to many important algebraic and combinato…

The enriched $q$ -monomial basis of the quasisymmetric functions

Darij Grinberg, Ekaterina A. Vassilieva

We construct a new family $(I^\cdot_{I^} \pm^{(q)})_{I^\pm \in Comp}$ of quasisymmetric functions for each element $q$ of the base ring. We call them the…

Betti Numbers and Higher Weight Spectra of Reed-Muller Codes $R M_{q} (2, 2)$

Sudhir R. Ghorpade, Trygve Johnsen, Rati Ludhani +1

We determine all the Betti numbers of the $q$ -ary second order Reed-Muller codes of length $q^{2}$ , and also of the elongations of matroids associated to these codes. We then use it…
