comment Does the closure of component set restricted to subspace equals to the closure of component set in the subspace?
So that means $Int_Y(A)=Y \cap Int_X(A)$ is also not true in general.

@Siminore I think not, because $X-A$ may not included in $Y$.

@David_Speyer Okay, it seems $\mathbb{C}$ cannot reduct to real vector space with real metric. But what about real vector space with complex metric? May $\mathbb{R}^2$ with metric matrix $\left(\begin{array}{cc}1&i\\i&-1\end{array}\right)$ describe $\mathbb{C}$ well?

Stokes' theorem works on smooth real manifolds, so I consider that if $\mathbb{C}$ can be seen as $\mathbb{R}^2$ but with metric matrix $\left(\begin{array}{cc}1&0\\0&-1\end{array}\right)$ $\ldots$
