The Primitivity of the Galois Group of a Trinomial

Journal of the London Mathematical Society, 1996
The primitivity of transitive permutation groups is examined in terms of conditions on a system of generators. The authors give a criterion of primitivity for the Galois group of an irreducible trinomial with integer coefficients of the form \(X^n+ ac^n X^s+ bc^n\) using the study of the inertia groups of primes in the splitting field of such ...

Primitivity in Free Groups and Free Metabelian Groups

Canadian Journal of Mathematics, 1992
AbstractLet Mn, c denote the free n-generator metabelian nilpotent group of class c. For m ≤ n – 2, every primitive system of m elements of Mn, c can be lifted to a primitive system of m elements of the absolutely free group Fn of rank n. The restriction on m cannot be improved.

On Primitive Solvable Linear Groups

Canadian Journal of Mathematics, 1971
Let V be a vector space over the field K. A group G of K-linear transformations of V onto itself is primitive in case no proper nontrivial subspace of V is G-invariant and V cannot be written as a direct sum of proper subspaces permuted among themselves by G.

The Structure of a Primitive Group

1996
In this chapter our focus changes from the combinatorial and ring theoretic representations of permutation groups considered in the last chapter to more direct group theoretic analysis of the groups involved. The point stabilizers of a primitive group form a conjugacy class of maximal subgroups, so classification of primitive groups is closely related ...

Action of primitive groups

Algebra and Logic, 1989
In the paper graphs of finite valency d are considered which admit a vertex primitive group of automorphisms. Theorem 1. Let \(d,r\in {\mathbb{N}}\) and \(f:{\mathbb{N}}\cup \{0\}\to {\mathbb{N}}\cup \{0\}\) such that \(f(n)=o(n)\) as \(n\to \infty.\) There exists a natural number c(d,f,r)\(\geq 1\) such that if G is a primitive group of automorphisms ...
