Definition

Symbol-free definition

A finite group is said to be linearly primitive if it has a faithful irreducible representation over an algebraically closed field of characteristic zero (or equivalently, over the algebraic closure of rationals or over the complex numbers).

Definition with symbols

A group $G$ is said to be linearly primitive if there is a homomorphism $\sigma :G\to GL(V)$ for some vector space $V$ over the complex numbers, such that $V$ has no proper nonzero $G$-invariant subspace.
