Some properties of a new partial order on Dyck paths
Algebraic Combinatorics, Volume 3 (2020) no. 2, pp. 433-463.

A new partial order is defined on the set of Dyck paths of a given length. This partial order is proved to be a meet-semilattice. Its intervals are enumerated and a specific interval is connected with an existing polytope coming from algebraic topology.
