Mortensen Observer for a class of variational inequalities -Lost equivalence with stochastic filtering approaches
L. P. Chaintron, Álvaro Mateos González, Laurent Mertz +1
We address the problem of deterministic sequential estimation for a nonsmooth dynamics in R governed by a variational inequality, as illustrated by the Skorokhod problem with a ref…

A piecewise deterministic Markov process approach modeling a dry friction problem with noise
Josselin Garnier, Ziyu Lu, Laurent Mertz
Understanding and predicting the dynamical properties of systems involving dry friction is a major concern in physics and engineering. It abounds in many mechanical processes, from…
