Abstract
Given any poset and chain in , we define the -Tamari lattice. We study in depth these lattices and prove in particular that they are join-semidistributive, join-congruence uniform and left modular. We prove that the lattices of higher torsion classes of the higher Auslander and Nakayama algebras of type are examples of -Tamari lattices and thus they inherit their properties. We also give general results related to left modular, extremal and congruence normal lattices.
