Seminários em Dinâmica não-linear
In this talk we consider the semilinear damped wave problem of the form
(α(t)ut)t − β(t)∆u + γ(t)ut + δ(t)u = β(t)f(u), x ∈ Ω, t > τ,
u(x, t) = 0, x ∈ ∂Ω, t > τ,
u(x, τ ) = uτ (x), ut(x, τ ) = vτ (x), x ∈ Ω,
where Ω is a bounded smooth domain in R
N , N > 3, τ ∈ R, f is a real valued function of a real variable with some suitable conditions of growth, regularity and dissipativity, and α, β, γ and δ are continuous real valued functions of a real variable with some suitable conditions of growth, regularity and signs. Using rescaling of time we prove existence, regularity, gradient-like structure, upper semicontinuity of the pullback attractors for the evolution processes associated with this boundary initial value problem in a suitable phase space.
This work is together with the professors PhD. Gleiciane S. Aragão (UNIFESP, Brasil), PhD. Marcelo J. D. Nascimento (UFSCar, Brasil) and PhD. Flank D. M. Bezerra (UFPB, Brasil). This work is financed by CAPES/Brazil (Finance Code 001/2019).
