Next Seminar of 2019.2

Propriedades Assintóticas para uma Equação de Onda Sob Efeito de Super Damping

Juan Carlos Torres Espinoza

Doutorado - UFSC
Neste seminário estudaremos o problema de Cauchy linear $$ \left\{ \begin{aligned} &u_{tt} − \Delta u + (-\Delta)^\theta u_t = 0, \hbox{ em } (0, \infty) \times \mathbb{R}^n\\ &u(0, x) = u_0 (x), \ u_t (0, x) = u_1 (x), \end{aligned} \right. $$ onde $\theta>0$ e os dados iniciais são escolhidos dentro do espaço de energia. Obteremos e estudaremos taxas de decaimento da solução e da energia associada na norma $L^2$. Usando uma expansão assintótica da solução do problema no espaço de Fourier, mostraremos otimalidade das taxas obtidas, considerando a norma $L^2$.
