Abstract

Motivated by recent results concerning the asymptotic behaviour of differential operators with highly contrasting coefficients, whose effective descriptions have involved generalised resolvents, we construct the functional model for a typical example of the latter. This provides a spectral representation for the generalised resolvent, which can be utilised for further analysis, in particular the construction of the scattering operator in related wave propagation setups.

广义解析子的函数模型及其在时间色散介质中的应用
最近的研究结果涉及具有高度对比系数的微分算子的渐近行为,其有效描述涉及广义分解项,受此激励,我们为后者的一个典型例子构建了函数模型。这为广义分解算子提供了光谱表示,可用于进一步分析,特别是在相关波传播设置中构建散射算子。
