comment What's $[L:K(\alpha)]$ here?
Are you familiar with the theorem of Artin that says that for a field $E$ and a finite group of automorphisms $G$ that $E/E^G$ is a Galois extension?

comment Given a polynomial $p(x)$ in $\mathbb Z_6[x]$, it is possible to construct a ring $R$ such that $p(x)$ has a root in $R$.
The integers modulo $6$ don't embed in the complex numbers, so there's no way to put make sense of applying a complex number to $p(x)$.

revised Given $A_1 = \{\emptyset\}$ and $A_{n+1} = A_n \cup (A_n \times A_n)$ define $A = \bigcup_{i=1}^\infty A_n$, what is $A\times A$?

comment The kernel of homomorphism of a local ring into a field is its maximal ideal?
Is $\phi$ surjective? Otherwise pick your favorite discrete valuation ring and look at the inclusion mapping into its field of fractions...
