,Maxwell’s equations,.6, we briefly treat exterior boundary value problems. Exterior boundary value problems and the existence of wave operators will be dealt with in Chapter 9 in more detail, where we shall present a unified approach to both Maxwell’s equations and the linearized system of acoustics.Vertebra 发表于 2025-3-23 14:51:12

Linear elasticity,and similarities with the wave equation. The main difference to the systems we have met so far is the fact that in linear elasticity different (non-zero) eigenvalues occur giving rise to different asymptotic behaviour of the corresponding components (cf. the remark after (9.18)).Entropion 发表于 2025-3-24 23:35:50
Linear thermoelasticity,ve met so far, the underlying operator is non-self-adjoint. Thus the spectral theorem is not applicable and we use semi-group theory instead. On the other hand there are many similarities to linear elasticity. Furthermore the solutions decompose into vibrating and damping terms.
