WebStated in this form, in the past the result was sometimes referred to as the Rellich–Kondrachov selection theorem, since one "selects" a convergent subsequence. (However, today the customary name is "compactness theorem", whereas "selection theorem" has a precise and quite different meaning, referring to multifunctions). Webforms. An important example of such techniques and results is the Rellich selection theorem[10, 30], which states that any weakly convergent sequence in H1(Ω) (or its closed subspace) for the bounded Lipschitz domain Ωis strongly convergent in L2(Ω).
