• Long-time dynamics of a hinged-free plate driven by a nonconservative force

  Annales de l Institut Henri Poincaré C Analyse Non Linéaire · 2022-02-25 · 19 citations

  articleOpen access

  A partially hinged, partially free rectangular plate is considered, with the aim of addressing the possible unstable end behaviors of a suspension bridge subject to wind. This leads to a nonlinear plate evolution equation with a nonlocal stretching active in the spanwise direction. The wind-flow in the chordwise direction is modeled through a piston-theoretic approximation, which provides both weak (frictional) dissipation and nonconservative forces. The long-time behavior of solutions is analyz…

• Maximal Lp-regularity of an abstract evolution equation: Application to closed-loop feedback problems, with boundary controls and boundary sensors

  Nonlinear Analysis Real World Applications · 2024-12-21 · 1 citations

  articleOpen access1st authorCorresponding

  We present an abstract maximal L p -regularity result up to T = ∞ on a Banach space, that is tuned to capture (linear) PDEs of parabolic type, defined on a bounded domain and subject to finite dimensional, boundary controls and boundary sensors, in feedback form. It improves Lasiecka et al. (2021), which covered boundary controls and interior sensors. The present proof must necessarily be completely different from the one in Lasiecka et al. (2021). In applications (Section 3), the case T < ∞ req…

• Uniform stabilization of the Boussinesq system in Besov spaces via finite dimensional, boundary-based fluid and interior thermal feedbacks

  Evolution equations and control theory · 2026-01-01

  articleOpen access1st authorCorresponding

  Let $ \Omega $ be an open, connected, bounded domain in $ \mathbb{R}^d, d = 2, 3, $ with boundary $ \Gamma = \partial \Omega $ of, say, class $ \mathrm{C}^2 $. Let $ \widetilde{\Gamma} $ be a connected, arbitrarily small portion of $ \Gamma $ and $ \omega $ be an arbitrarily small collar in $ \Omega $, supported by $ \widetilde{\Gamma} $ [Figure 2]. In $ \Omega $, we consider a Boussinesq system subject to a control triplet: $ \{\mathbf{{v}}, \mathbf{{u}}, g\} $. Here, $ \mathbf{{v}} $ is a loca…

• Stability and Gevrey regularity of the semigroup associated with an Euler–Bernoulli plate equation subject to localized Kelvin–Voigt damping

  Journal of Evolution Equations · 2026-01-19

  articleOpen access1st authorCorresponding

  Abstract We consider an Euler–Bernoulli plate equation with Kelvin–Voigt damping in a bounded domain. The damping is localized in an appropriate open strict subset $$\omega $$ <mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML"> <mml:mi>ω</mml:mi> </mml:math> of the domain $$\Omega $$ <mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML"> <mml:mi>Ω</mml:mi> </mml:math> . While it is known that the solutions of this model with a full damping $$\omega = \Omega $$ <mml:math xmlns:mml="http:…
