Sobolev space inclusions

126 Views Asked by At

Suppose $\Omega$ is bounded. Then, is it true that $W_0^{1,q}(\Omega)\subset W_0^{1,p}(\Omega)$ whenever $p\leq q$? It seems like it should certainly be true since we do know that $L^q(\Omega)\subset L^p(\Omega)$ under the same hypothesis. But I'm wondering if I'm missing a subtlety.
