Hopf Algebras of Graphs
Jean-Christophe Novelli, Jean-Yves Thibon, Nicolas M. Thiéry
We define graded Hopf algebras with bases labeled by various types of graphs and hypergraphs, provided with natural embeddings into an algebra of polynomials in infinitely many var…

Algebraic invariants of graphs; a study based on computer exploration
Nicolas M. Thiéry
We consider the ring I_n of polynomial invariants over weighted graphs on n vertices. Our primary interest is the use of this ring to define and explore algebraic versions of isomo…

Hecke group algebras as quotients of affine Hecke algebras at level 0
Florent Hivert, Anne Schilling, Nicolas M. Thiéry
The Hecke group algebra of a finite Coxeter group , as introduced by the first and last author, is obtained from by gluing appropriately its 0-Hecke algebra and i…
