Abstract:
A novel approach to critical-contrast homogenisation is proposed. Norm-resolvent asymptotics are explicitly constructed. An essential feature of our approach is that it relates homogenisation limits to a class of time-dispersive media.
Key words and phrases:
Homogenisation, critical-contrast, time dispersion, graphs, dilation, generalised resolvent.
