A geometric condition for the uniform stability of linear magnetoelasticity
نویسندگان
چکیده
We give a necessary and sufficient condition, of geometrical type, for the uniform decay energy solutions linear system magnetoelasticity in bounded domain with smooth boundary. A Dirichlet-type boundary condition is assumed. Our strategy to use microlocal defect measures show suitable observability inequalities on high-frequency Lamé system.

investigating the feasibility of a proposed model for geometric design of deployable arch structures
deployable scissor type structures are composed of the so-called scissor-like elements (sles), which are connected to each other at an intermediate point through a pivotal connection and allow them to be folded into a compact bundle for storage or transport. several sles are connected to each other in order to form units with regular polygonal plan views. the sides and radii of the polygons are...
Uniform Smoothed Analysis of a Condition Number for Linear Programming
Bürgisser, Cucker, and Lotz [arxiv:math.NA/0610270] proved a general theorem providing smoothed analysis estimates for conic condition numbers of problems of numerical analysis. Applications to linear and polynomial equation solving were given. We show that a suitable modification of the general theorem in that paper, adapted to a spherical convex setting, allows to analyze condition numbers of...
متن کاملStabilization of the Linear System of Magnetoelasticity
We give a necessary and sufficient condition, of geometrical type, for the uniform decay of energy of solutions of the linear system of magnetoelasticity in a bounded domain with smooth boundary. A Dirichlet-type boundary condition is assumed. When the geometrical condition is not fulfilled, we show polynomial decay of the energy, for smooth initial conditions. Our strategy is to use micro-loca...
