| Mar 25 at 7:32 | comment | added | Zhang Yuhan | It seems the boundedness of the domain important for the equivalence. For if $\Omega = \mathbb R^n$ the space $L^2_0(\Omega)$ would be undefined and the range of $\operatorname{div}: H_0^1(\Omega)\to L^2(\Omega)$ would not be closed. I wonder are there proofs of J.C. Lions lemma that makes no use of Fourier analysis when $\Omega$ unbounded. | |
