"WebApr 9, 2024 · To do a base change between two fields, you need a homomorphism between those fields. More generally for changing scalars from some ring $R$ to some other ring $S$, you need some homomorphism $R \rightarrow S$; which, for fields, will always be plain inclusions $K \subset L$. So it's easy to change scalars from $\mathbb R$ to $\mathbb C$. " - Chevalley basis of a2
