[1]、[2] 证明,在奇数维空间中,局部能量的任何均匀衰减都意味着它必须呈指数衰减。我们将其扩展到偶维空间和更一般的扰动(包括传输问题),表明局部能量的任何均匀衰减都意味着它必须像 O(t) 一样衰减,t ≫ 1 是时间,n 是空间维度。
It is proved in [1],[2] that in odd dimensional spaces any uniform decay of the local energy implies that it must decay exponentially. We extend this to even dimensional spaces and to more general perturbations (including the transmission problem) showing that any uniform decay of the local energy implies that it must decay like O(t), t ≫ 1 being the time and n being the space dimension.
