Abstract:
Both the noncrossing partition/Kreweras lattice and parking functions are well-studied objects in combinatorics. In 1997 Richard Stanley found a bijection between the maximal chains in the lattice and parking functions. We investigated what happens under the
bijection when we restrict the noncrossing partition lattice to certain induced sublattices (certain bond lattices). I will describe these all the lattices involved, and the enumeration of maximal chains
in them, as well as discuss the image of Stanley's map. I will also describe how we map the maximal chains to unimodal forests. This is joint with Shreya Ahirwar, Davy Brooks, Parikshita Gya, Pamela
