Combinatorial twisted bialgebras and combinatorial twisted double bialgebras
Lo{ï}c Foissy
We provide in this text a new framework for a family of combinatorial Hopf algebras. We adopt for this the language of species and twisted bialgebras (also known as Hopf monoids).…
Bialgebraic structures on boolean functions
Loïc Foissy
We study several bialgebraic structures on boolean functions, that is to say maps defined on the set of subsets of a finite set , taking the value on . Examples o…
Operads and bialgebras of multi-indices, and Novikov algebras
Loïc Foissy
Noncommutative multi-indices are noncommutative monomials in a -indexed family of indeterminates. We define on them a -graded operadic structure, with the h…
Cocycle weighted infinitesimal bialgebras and pre-Lie algebras on rooted trees
Loïc Foissy, Yunzhou Xie, Dawei Zhang +1
The concept of weighted infinitesimal bialgebras provides an algebraic framework for understanding the non-homogeneous associative Yang-Baxter equation. In this paper, we endow the…
Construction of pre-and post-Lie algebras for stochastic PDEs
Loïc Foissy
We give and study a construction of pre-Lie algebra structures on rooted trees whose edges and vertices are decorated, with a grafting product acting, through a map , both on th…
Matrix symmetric and quasi-symmetric functions and noncommutative representation theory
Loïc Foissy, Claudia Malvenuto, Frédéric Patras
A fundamental result by L. Solomon in algebraic combinatorics and representation theory states that Mackey formulas for products of characters of a symmetric group, or equivalently…
