In a work of mine, I need the following subspace of $H^1(\mathbb{R})$: $$ \{u \in H^1(\mathbb{R}):u(0)=0\}. $$ I first used the notation $H_0^1(\mathbb{R})$ for it but a referee did not like that because he says it refers to something else. Does anyone know the correct notation or have a suggestion as to what I could use?
