That is all correct. A field satisfies all ring axioms plus some extra axioms, so a field is a ring. A ring is an Abelian group plus some more axioms, so each ring is a group.
A vector spac... | Every vector space is *over a field*. And every field is a vector space over itself.
So for instance $\Bbb R$ is a field. But we can also say that $\Bbb R$ is a vector space over the field $\Bbb R$. Likewise $\Bbb C$ can be considered a vector space over $\Bbb C$ (making it a one-dimensional vector space). Also $\Bbb ... |
