Procesi’s Conjecture on the Formanek-Weingarten Function is False
Comptes Rendus. Mathématique, Tome 360 (2022) no. G10, pp. 1169-1172.

In this paper, we disprove a recent monotonicity conjecture of C. Procesi on the generating function for monotone walks on the symmetric group, an object which is equivalent to the Weingarten function of the unitary group.
