Abstract
We investigate the asymptotic convergence of the trajectories generated by the second-order dynamical system , where
are the convex and smooth functions defined on a real Hilbert space
,
and
is a function of time which controls the penalty term. We show weak convergence of the trajectories to a minimizer of the function
over the (nonempty) set of minima of
as well as convergence for the objective function values along the trajectories, provided a condition expressed via the Fenchel conjugate of
is fulfilled. When the function
is assumed to be strongly convex, we can even show strong convergence of the trajectories. The results can be seen as the second-order counterparts of the ones given by Attouch and Czarnecki (Journal of Differential Equations 248(6), 1315–1344, 2010) for first-order dynamical systems associated to the constrained variational inequalities. At the same time we give a positive answer to an open problem posed by Attouch and Czarnecki in a recent preprint.
