Primitive Elements of the Hopf Algebras of Tableaux

Autor: 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, Schuetzenberger's "jeu de taquin", and evacuation. In 1995 Poirier and th

International audience; 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 calculus approach to the latter. We propose in par

A theory of pictures for quasi-posets

Journal of Algebra, Elsevier, 2017, 477, pp.496-515

International audience; 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 reasons, com-binatorial (e.g. since semi-standa

A self paired Hopf algebra on double posets and a Littlewood–Richardson rule

Autor: Claudia Malvenuto, Christophe Reutenauer

Publikováno v: Journal of Combinatorial Theory, Series A. 118(4):1322-1333

Let D be the set of isomorphism types of finite double partially ordered sets, that is sets endowed with two partial orders. On ZD we define a product and a coproduct, together with an internal product, that is, degree-preserving. With these operatio

Pairwise colliding permutations and the capacity of infinite graphs

Autor: János Körner, Claudia Malvenuto

Publikováno v: SIAM Journal on Discrete Mathematics. 20:203-212

We call two permutations of the first n naturals colliding if they map at least one number to consecutive naturals. We give bounds for the exponential asymptotics of the largest cardinality of any set of pairwise colliding permutations of [n]. We rel

The Hopf algebra of finite topologies and T-partitions

Autor: Claudia Malvenuto, Loïc Foissy

A noncommutative and noncocommutative Hopf algebra on finite topologies H_T is introduced and studied (freeness, cofreeness, self-duality...). Generalizing Stanley's definition of P-partitions associated to a special poset, we define the notion of T-

International audience; Finite topological spaces are in bijective correspondence with preorders on finite sets. We undertake their study using combinatorial tools that have been developed to investigate general discrete structures. A particular emph

Plethysm and conjugation of quasi-symmetric functions

Autor: Claudia Malvenuto, Christophe Reutenauer

Publikováno v: Discrete Mathematics. 193:225-233

Let F C denote the basic quasi-symmetric functions, in Gessel's notation (1984) ( C any composition). The plethysm s λ oF C is a positive linear combination of functions F D . Under certain conditions, the image under the involution ω of a quasi-sy
