    Markov dynamics on branching graphs of diagram algebras

    Résumé : Thoma’s famous theorem on the classification of characters on
    the infinite symmetric group has been very influential in different
    areas of mathematics such as combinatorics and probability theory. In
    this talk, we explain versions of Thoma’s theorem for different diagram
    algebras arising out of subfactor theory and Banica and Speicher’s
    theory of easy quantum groups. As Thoma’s classical theorem, these
    results can be formulated in a probabilistic language and we find
    interesting new connections to random lattice paths and random walks on
    trees.
