Weighted Decay Estimates for the Wave Equation with Radially Symmetric Data
نویسنده
چکیده
Abstract. We study the homogeneous wave equation with radially symmetric data in n ≥ 4 space dimensions. Using some new integral representations for the Riemann operator, we estimate the L∞-norm of the solution. Our results refine those of Kubo [2, 3] in odd space dimensions as well as those of Kubo and Kubota [5] in even space dimensions. However, our approach does not really depend on the parity of n.

Regularity and Scattering for the Wave Equation with a Critical Nonlinear Damping
We show that the nonlinear wave equation u + ut = 0 is globally well-posed in radially symmetric Sobolev spaces Hk rad(R 3) × Hk−1 rad (R 3) for all integers k > 2. This partially extends the well-posedness in Hk(R3) × Hk−1(R3) for all k ∈ [1, 2], established by Lions and Strauss [12]. As a consequence we obtain the global existence of C∞ solutions with radial C∞ 0 data. The regularity problem ...

We obtain large time decay estimates on weighted L spaces, 2 < p < +∞, for solutions to the wave equation with real-valued potential V (x) = O(〈x〉−2−δ0 ), δ0 > 0.
متن کاملDecay estimates of solutions to the IBq equation
In this paper we focus on the Cauchy problem for the generalized IBq equation with damped term in $n$-dimensional space. We establish the global existence and decay estimates of solution with $L^q(1leq qleq 2)$ initial value, provided that the initial value is suitably small. Moreover, we also show that the solution is asymptotic to the solution $u_L$ to the corresponding linear equa...
متن کاملDecay estimates of solutions to wave equations in conical sets
We consider the wave equation in an unbounded conical domain, with initial conditions and boundary conditions of Dirichlet or Neumann type. We give a uniform decay estimate of the solution in terms of weighted Sobolev norms of the initial data. The decay rate is the same as in the full space case.
متن کاملTraveling Waves of Some Symmetric Planar Flows of Non-Newtonian Fluids
We present some variants of Burgers-type equations for incompressible and isothermal planar flow of viscous non-Newtonian fluids based on the Cross, the Carreau and the power-law rheology models, and on a symmetry assumption on the flow. We numerically solve the associated traveling wave equations by using industrial data and in order to validate the models we prove existence and uniqueness of ...
