Fault Detection for Lipschitz Nonlinear Systems With Restricted Frequency-Domain Specifications

IEEE Transactions on Systems, Man, and Cybernetics: Systems, 2021
This article deals with the problem of fault detection for discrete-time Lipschitz nonlinear systems subject to a class of restricted frequency-domain specifications. We present a novel observer structure with more design parameters, which can be applied

On a Time-Dependent Transport Equation in a Lipschitz Domain

SIAM Journal on Mathematical Analysis, 2010
We prove uniqueness of the solution of a time-dependent transport equation with a divergence-free driving velocity that is $L^1$ in time and $H^1$ in space, in a Lipschitz domain of $\mathbb{R}^d$, tangential on the boundary. The proof is done by regularization with a special mollifier.

ON THE MINIMAL THINNESS IN A LIPSCHITZ DOMAIN

Analysis, 1983
Let D be a bounded Lipschitz domain in \({\mathbb{R}}^ n\), \(n\geq 3\). The author proves the following extensions of results of \textit{J. Lelong- Ferrand} [Ann. Sci. Éc. Norm. Supér., III. Sér. 66, 125-159 (1949; Zbl 0033.373)]. If \(E\subseteq D\) and E is thin at \(\xi\in \partial D\), then E is minimally thin at \(\xi\).

On the stokes problem in Lipschitz domains

Annali di Matematica Pura ed Applicata, 1994
The authors consider the Stokes problem in a bounded domain \(\Omega \subset \mathbb{R}^ n (n \geq 2)\), i.e. \[ - \Delta u + \nabla p = f, \text{ div} u = g\quad\text{in } \Omega,\quad u = \varphi\quad\text{on } \partial \Omega \tag{*} \] where \(\partial \Omega\) is only assumed to be Lipschitz.
