Math 361, Spring 2015, Assignment 12

Carefully define the following terms, then give one example and one non-example of each:

1. Additive representation (of $GF(p^n)$).
2. Multiplicative representation (of $GF(p^n)$).

Carefully state the following theorems (you do not need to prove them):

1. Primitive element theorem.
2. Theorem concerning degrees of irreducible polynomials in $\mathbb{Z}_p[x]$.
3. Classification of subfields of $GF(p^n)$.
4. Theorem describing the algebraic closure of $\mathbb{Z}_p$ (this will necessarily be a somewhat imprecise statement, since we have not formally defined the term direct limit, and the meaning of "union" in this context is not quite clear).

Solve the following problems:

1. Section 33, problems 1, 3, 4, and 11.
