DESCRIPTION:Speaker: Lang Mou (UC Davis)\n\nTitle: Leafy trees\, wall-cros
 sing\, and m-Tamari intervals\n\nAbstract: Trees appear in several approa
 ches to wall-crossing. I will present a new plane-tree model for the cent
 ral wall in rank-2 cluster scattering diagrams\, inspired by the recently
  introduced tight gradings on Dyck paths. These trees turn out to be in b
 ijection with intervals in the m-Tamari lattice\, a lattice on m-ballot p
 aths. I will explain this correspondence and show how the tree perspectiv
 e leads to algebraic functional equations for enumerating these intervals
  and a new combinatorial proof of the central wall formula. No prior know
 ledge of wall-crossing or cluster algebras will be assumed. This talk is 
 based on joint work with Amanda Burcroff and Kyungyong Lee.\n\nhttp://nex
