Resumen:
We consider the class of quadratically constrained quadratic
programming methods in the framework extended from optimization to more
general Karush-Kuhn-Tucker systems (which can be related, for example,
to variational inequalities). Previously, Anitescu showed superlinear
convergence of the primal sequence under the Mangasarian-Fromovitz
constraint qualification and the quadratic growth condition. Quadratic
convergence of the primal-dual sequence was established by Fukushima,
Luo and Tseng under the convexity assumption, the Slater constraint
qualification, and a strong second-order sufficient condition. We obtain
a new local result, different from the above (it is neither stronger
nor weaker): we prove primal-dual quadratic convergence under the linear
independence constraint qualification, strict complementarity, and a
second-order sufficiency condition. Additionally, we provide a necessary
and sufficient condition for superlinear convergence of the primal
sequence under a Dennis-Moré type condition.
