Homogenization of the wave equation
Patrizia Donato · 1999
Abstract In this chapter we are concerned with the asymptotic behaviour as ε → 0 of the solution u ε = u ε (x, t) of the wave equation introduced in Section 5.2 (Example 5.3), namely, where as in the previous chapter, the operators div and ▽ are taken with respect to the space variable x ∈ Ω and ‘ denotes the derivative with respect to the time variable l ∈]0, T[ with T > 0.
