Orders of algebraic numbers in finite fields

Olli Järviniemi

For an algebraic number $α$ we consider the orders of the reductions of $α$ in finite fields. In the case where $α$ is an integer, it is known by the work on Artin's primitive root…

On the Common Prime Divisors of Polynomials

Olli Järviniemi

The prime divisors of a polynomial $P$ with integer coefficients are those primes $p$ for which $P (x) \equiv 0 (mod p)$ is solvable. Our main result is that the common prime divis…

Equality of orders of a set of integers modulo a prime

Olli Järviniemi

For finitely generated subgroups $W_{1}, \dots, W_{t}$ of $Q^{\times}$ , integers $k_{1}, \dots, k_{t}$ , a Galois extension $F$ of $Q$ and a union of conjugacy classes…

Simultaneous insolvability of exponential congruences

Olli Järviniemi

We determine a necessary and sufficient condition for the infinitude of primes $p$ such that none of the equations $a_{i}^{x} \equiv b_{i} (mod p), 1 \leq i \leq n,$ are solvable. We cont…
