Generating tuples of integers modulo the action of a permutation group and applications
Nicolas Borie
Originally motivated by algebraic invariant theory, we present an algorithm to enumerate integer vectors modulo the action of a permutation group. This problem generalizes the gene…
Construction d'opérades ensemblistes à partir de monoïdes
Samuele Giraudo
We study a functorial construction from the category of monoids to the category of set-operads and we give some combinatorial examples of applications.
Multivariate Polynomials in Sage
Viviane Pons
We have developed a patch implementing multivariate polynomials seen as a multi-base algebra. The patch is to be released into the software Sage and can already be found within the…
Algebraic and combinatorial structures on pairs of twin binary trees
Samuele Giraudo
We give a new construction of a Hopf algebra defined first by Reading whose bases are indexed by objects belonging to the Baxter combinatorial family (i.e., Baxter permutations, pa…
