Asymptotics of solutions to the periodic problem for the nonlinear damped wave equation

Abstract: Abstract.We study large time asymptotic behavior of solutions to the periodic problem for the nonlinear damped wave equationwhere Ω = [−π, π] , α, β, λ, σ > 0. We prove that if the initial data φ ∈ H 1 and ψ ∈ L 2 , then there exists a unique solution u (t, x) ∈ C [0, ∞) ; H 1 of the periodic problem which has the time decay estimatesfor all t > 0. Moreover under some additional conditions we find the asymptotic formulas for the solutions. Mathematics Subject Classification (2000). 35L15, 35K20.

“…For the Benjamin-Bona-Mahony-Peregrine-Burgers equation, the existence of global solutions and decay estimates of energy were obtained in paper [26]. Asymptotics of solutions to the periodic problem for the nonlinear damped wave equation was studied in paper [14]. Large time behavior of solutions to the periodic problem for systems of conservation laws was studied in [8,24].…”
