Things to do:

Definition:Differential
Let $(E, \| \cdot \|_E)$, $(F, \| \cdot \|_F)$ be normed vector spaces.

Let $U \subseteq E$ be an open set.

Let $f : U \to F$ be a mapping.

Let $a \in U$ be an element of $U$.

Then $f$ is differentiable at $a$ if there exists a continuous and linear map $df_a \in \mathcal L(E,F)$ such that


 * $\displaystyle \lim_{h \to 0} \| f(a+h) - f(a) - df_a \cdot h \|_F \| h \|_E^{-1} = 0$

Then $df_a$ is called the differental or the tangent map of $f$ at $a$.

We say that $f$ is continuously differentiable if:
 * $\displaystyle df : (U, \| \cdot \|_E) \to \mathcal (L(E,F),\| \cdot \|_{L(E,F)})$
 * $\displaystyle \ : a \mapsto df_a$

is continuous.

If $E = \R^n$, this is true iff the first order partial derivatives of $f$ exist and are continuous.

Induced polynomial homomorphism
Even this needs serious thought if it's to be any good.

Permutations
Definition:Cyclic Permutation $k$ well defined. Add canonicality.

Incorrect: Definition:Permutation on n Letters/Cycle Notation permutation/cycle confusion? Also $\rho$ should be $\pi$ for consistency.

Then here: Equality of Cycles

Rings, properties, equivalent definitions
GCD domain:
 * Equivalent Definitions of a GCD Domain
 * Properties of GCD Domains

Bézout domain
 * Equivalent Definitions of a Bézout domain
 * Properties of Bézout Domains

Definition:Unique Factorization Domain:
 * Equivalent Definitions of a Unique Factorization Domain
 * Properties of Unique Factorization Domains

etc...needs organizing into something more standardized

The rest

 * Vinogradov's Theorem: Pick a method of proof and think of a good structure for it.


 * Figure out conditions for the "function-form epimorphism" to have trivial kernel (see Epimorphism from Polynomial Forms to Polynomial Functions and especially Equality of Polynomials)
