Article Description

For the wave equation α2uαt2 = Σi=iN α2uαxi2 (for t ϵ R and ξ ϵ R N one could think that the natural associated energy space might be K := H 1 ( R N ) × L 2 ( R N ). This is misleading and only partially correct. The purpose of this paper is to explain the role of the energy spaces associated with a wave equation. This is done in an abstract context, when the negative Laplacian is replaced by an arbitrary nonnegative self-adjoint operator on a Hilbert space. For the wave equation on κ, the norm of the governing group of operators is shown to grow linearly in time (as t → ±∞).
