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…

The Fortuin-Kasteleyn polynomial as a bialgebra morphism and applications to the Tutte polynomial

Loïc Foissy, Claudia Malvenuto

We compute an explicit formula for the antipode of the double bialgebra of graphs in terms of totally acyclic partial orientations, using some general results on double bialgebras.…

Primitive Elements of the Hopf Algebras of Tableaux

Claudia Malvenuto, Christophe Reutenauer

The character theory of symmetric groups, and the theory of symmetric functions, both make use of the combinatorics of Young tableaux, such as the Robinson-Schensted algorithm, Sch…

A theory of pictures for quasi-posets

Loïc Foissy, Claudia Malvenuto, Frédéric Patras

The theory of pictures between posets is known to encode much of the combinatorics of symmetric group representations and related topics such as Young diagrams and tableaux. Many r…

Symmetril Moulds, Generic Group Schemes, Resummation of Mzvs

Claudia Malvenuto, Frédéric Patras

The present article deals with various generating series and group schemes (not necessarily affine ones) associated with MZVs. Our developments are motivated by Ecalle's mould calc…

The Hopf algebra of finite topologies and T-partitions

Loïc Foissy, Claudia Malvenuto

A noncommutative and noncocommutative Hopf algebra on finite topologies H_T is introduced and studied (freeness, cofreeness, self-duality...). Generalizing Stanley's definition of…
