FS 18


Research topics:

  • algebraic combinatorics, and in particular combinatorics in the symmetric group algebra and its representations (Young diagrams, factorizations in symmetric groups and associated graphs embedded in surfaces, Jucys-Murphy elements) ;
  • symmetric functions, including Jack polynomials, and generalizations (in particular quasi-symmetric functions) ;
  • continuous limits of discrete objects, in particular random permutations and random Young diagrams (my favorite tool in this framework is the combinatorial analysis of mixed cumulants) ;
  • linear extensions, hook formulas, $P$-partition theory.
