Observe that the upper boundary of the thin domain presents a highly oscillatory behavior and, moreover, the height of the thin domain, the amplitude and period of the oscillations are all of the same order, given by the small parameter ϵ.engjournal articlehttp://www.sciencedirect.com/science/journal/00217824open access517.9Thin domainOscillating boundaryHomogenizationExtension operatorEcuaciones diferenciales1202.07 Ecuaciones en Diferencias
