summary: Pipe dreams were introduced by Bergeron and Billey in order to study Schubert polynomials
and encode the algebraic structure of the symmetric group. In particular, with well-chosen parameters,
they have the combinatorial structure of the Tamari lattice, a well-known quotient of the weak order
on permutations. In this presentation ...
