چکیده

We derive decay rates for the energy of solutions of dissipative wave equations. The metod of proof combines multiplier techniques and the construction of suitable Lyapunov functionals. Without imposing any growth condition at the origin on the nonlinearity we show that this Lyapunov functional, which is equivalent to the energy of the system, is bounded above by the solution of a differential inequality that tends to zero as time goes to infinity.

The Energy Decay Problem for Wave Equations with Nonlinear Dissipative Terms in R

We study the asymptotic behavior of energy for wave equations with nonlinear damping g(ut) = |ut|m−1ut in Rn (n ≥ 3) as time t → ∞. The main result shows a polynomial decay rate of energy under the condition 1 < m ≤ (n+2)/(n+1). Previously, only logarithmic decay rates were found.

The Generalized Diffusion Phenomenon and Applications

We study the asymptotic behavior of solutions to dissipative wave equations involving two non-commuting self-adjoint operators in a Hilbert space. The main result is that the abstract diffusion phenomenon takes place, as solutions of such equations approach solutions of diffusion equations at large times. When the diffusion semigroup has the Markov property and satisfies a Nash-type inequality,...

Decay Estimates for Wave Equations with Variable Coefficients

We establish weighted L2−estimates for dissipative wave equations with variable coefficients that exhibit a dissipative term with a space dependent potential. These results yield decay estimates for the energy and the L2−norm of solutions. The proof is based on the multiplier method where multipliers are specially engineered from asymptotic profiles of related parabolic equations.

Rayleigh Wave in an Initially Stressed Transversely Isotropic Dissipative Half-Space

The governing equations of a transversely isotropic dissipative medium are solved analytically to obtain the surface wave solutions. The appropriate solutions satisfy the required boundary conditions at the stress-free surface to obtain the frequency equation of Rayleigh wave. The numerical values of the non-dimensional speed of Rayleigh wave speed are computed for different values of frequency...

Decay Characterization for Solutions to Dissipative Equations in Terms of the Initial Datum

By examining the Fourier transform of the initial datum near the origin, we define the decay character of the datum and provide a method to study the lower and upper algebraic rates of decay of solutions to a wide class of dissipative system of equations.
