The Steep-Bounce Zeta Map in Parabolic Cataland
Cesar Ceballos, Wenjie Fang, Henri Mühle
As a classical object, the Tamari lattice has many generalizations, including -Tamari lattices and parabolic Tamari lattices. In this article, we unify these generalizations in…

Tamari Lattices for Parabolic Quotients of the Symmetric Group
Henri Mühle, Nathan Williams
We generalize the Tamari lattice by extending the notions of -avoiding permutations, noncrossing set partitions, and nonnesting set partitions to parabolic quotients of the sy…
