Manytamaris: on descriptions of the Tamari lattice

-- Hoan La (LISN, Galac)

Time: 10:00 -- Location: LRI, 445

summary: Manytamaris is a website about the Tamari lattice. The interest in this particular lattice stems from its many properties, besides being a lattice, and its numerous appearances in different areas of mathematics. As such, the goal for Manytamaris is to be a survey on the descriptions of the Tamari lattice with many contributors. Furthermore, since Manytamaris is a website, it can be seen as a constantly updated and accessible survey.
Currently, the wiki shows how the Tamari lattice can be defined on Catalan objects; most notably the original definition by Huang and Tamari in 1972. To show that it is indeed the same lattice defined over these objects, the wiki presents some bijections and poset isomorphisms.
I will present what is currently on the wiki and what is planned for the future.
