Polynomial Internal and External Stability of Well-posed Linear Systems,p. Using these concepts, the polynomial stability of the given ..-semigroup governing the state equation can be characterized via polynomial bounds on the transfer function. We further give sufficient conditions for polynomial stabilizability and detectability in terms of decompositions into a polyn浮夸 发表于 2025-3-25 16:46:22

Multiscale Unique Continuation Properties of Eigenfunctions,perators and control theory..We review recent results and announce new ones regarding quantitative unique continuation principles for partial differential equations with an underlying multiscale structure. They concern Schrödinger and second-order elliptic operators. An important feature is that theCANDY 发表于 2025-3-26 07:27:38
Estimates on Non-uniform Stability for Bounded Semigroups,maginary axis. In , Charles J.K. Batty and the author have given an estimate of the decay of the operator norm of ., as . tends to infinity, in terms of asymptotic bounds of the resolvent of A on the imaginary axis. In this note, we give another proof of this result. The original proof relied onGLADE 发表于 2025-3-26 11:19:25
