Generic dynamics for evolution groups and $C_0$-semigroups on Hilbert spaces
(Universidade Federal de Minas GeraisUFMG, 2019-05-10)
In this thesis, we study the typical behaviour (from the topological viewpoint) of the decaying rates of the orbits of unitary evolution groups and C0-semigroups on Hilbert spaces. We have found that: (1) some dynamical ...
Optimal stability results for laminated beams with Kelvin-Voigt damping and delay
(Elsevier Inc.US, 2022)
We use semigroup theory to prove the well-posedness and get exponential and polynomial stability estimates for a delayed laminated beam system with Kelvin-Voigt damping. The Kelvin-Voigt damping only acts either on the ...
Laminated beams with thermoelasticity acting on the shear force
(John Wiley & Sons, Ltd.DE, 2023)
In this paper, we study the stabilization of a laminated beam system under the action of a new thermal coupling. Motivated by the work of Almeida Júnior et al. in the context of the Timoshenko system, we consider a ...
Stability results for a laminated thermoviscoelastic system with Fourier’s law
(BirkhauserCH, 2022)
In this paper, we study the qualitative behavior of a mathematical model for two-layered beams with Kelvin–
Voigt damping acting at the shear angle. The model describes the behavior of two-layered beams in which slip can ...
High-Order AFEM for the Laplace–Beltrami Operator: Convergence Rates
(Springer, 2016-12)
We present a new AFEM for the Laplace–Beltrami operator with arbitrary polynomial degree on parametric surfaces, which are globally W∞1 and piecewise in a suitable Besov class embedded in C1 , α with α∈ (0 , 1 ]. The idea ...
Asymptotics for the heat kernel in multicone domains
(Elsevier, 2016)
A multicone domain Omega subset of R-n is an open, connected set that resembles a finite collection of cones far away from the origin. We study the rate of decay in time of the heat kernel p(t, x, y) of a Brownian motion ...
Nonuniform laminated beam of Lord–Shulman type
(John Wiley and Sons IncGB, 2022)
The nonuniform thermoelastic laminated beam of the Lord–Shulman type is considered. The model is a two-layered beam with structural damping due to the interfacial slip. The well-posedness is proved by the semigroup theory ...
On the Characterization of l(p)-Compressible Ergodic Sequences
(IEEE-INST Electrical Electronics Engineers, 2015)
This work offers a necessary and sufficient condition for a stationary and ergodic process to be l(p)-compressible in the sense proposed by Amini, Unser and Marvasti ["Compressibility of deterministic and random infinity ...
