A finite field is a field with a finite number of elements. For each prime power $q^k$, there is a unique (up to isomorphism) finite field with $q^k$ elements. Up to isomorphism, these are the only finite fields.

additive structure in a small multiplicative group of a finite field?
Let $p$ be a prime. Given a positive integer $n$, does there exist a
$\beta$ in an extension of $F_p$ such that
1) If $F_p[\beta] = F_{p^N}$, then $N > n^n$; ( $\beta$ lies in a high extension)
2) …

Number of solutions of a linear equation in a small subset.
Let $p$ be a prime. Let $F_p$ be the finite field of
$p$ elements. Let $A$ be a subset of $F_p$ of size $s$.
Assume that $s > 2$ is polylogarithmic in $p$.
Suppose that we want to count number o …

Eigenvalue of a linear map over finite field
Let $ F_q $ be a finite field with $ q $ elements.
Let $ g $ be a multiplicative generator of $ F_{q^2}^* $.
It implies that
$ <g^{q+1}> = F_q^* $.
Let $ l $ be a prime greater than $ q^2-1 $ and …

Eigenvalues of the Cayley-like graph
Let $ F_q $ be a finite field of characteristic 2.
Let $ x^2 + Sx +P \in F_q[x] $ be an irreducible polynomial over $ F_q $,
and let $ g $ be one of its roots in $ F_{q^2} $.
Define a map $ M: F_{q^2 …
