Alessandro Iraci (UQAM): Tiered trees, Theta operators, Delta conjectures
Abstract: Theta operators are a family of operators on symmetric functions that have been introduced in order to state a compositional version of the Delta conjecture, with the idea, later proved successful, that this would have led to a proof via the Carlsson-Mellit Dyck path algebra. Theta operators show remarkable combinatorial properties; we are going to...
