Fix a prime p and finite field k of order q: = pr. For a field automorphism τ of k and a k-vector space V of dimension g, we will write Endτ (V) for the set of τ-semilinear endomorphisms of V; that is, additive maps F: V → V which satisfy F (αv) = τ(α) · F (v) for all v ∈ V and α ∈ k. As τ is an automorphism, the kernel and image (as sets, say) of any τ-semilinear map F are bot
