Description
The number of indecomposable non-injective projective modules minus the number of indecomposable non-injective projective modules that have reflexive Auslander-Reiten sequences in the corresponding Nakayama algebra. Here an indecomposable non-injective projective module P is said to have reflexive Auslander-Reiten sequences in case every term in the Auslander-Reiten sequence for P is reflexive. The Dyck paths where the statistic returns the value 0 are of special interesting, see [1].
