In this paper, we deal with a conjecture formulated in Andreani et al. (Optimization 56:529-542, 2007), which states that whenever a local minimizer of a nonlinear optimization problem fulfills the Mangasarian-Fromovitz constraint qualification and the rank of the set of gradients of active constraints increases at most by one in a neighborhood of the minimizer, a second-order optimality condition that depends on one single Lagrange multiplier is satisfied. This conjecture generalizes previous results under a constant rank assumption or under a rank deficiency of at most one. We prove the conjecture under the additional assumption that the Jacobian matrix has a smooth singular value decomposition. Our proof also extends to the case of the strong second-order condition, defined in terms of the critical cone instead of the critical subspace. (AU)
