Twisted Centralizer Codes

Adel Alahmadi, S. P. Glasby, Cheryl E. Praeger +2

Given an $n \times n$ matrix $A$ over a field $F$ and a scalar $a \in F$ , we consider the linear codes $C (A, a) := {B \in F^{n \times n} ∣ A B = a B A}$ of length $n^{2}$ . We call $C (A, a)$ …

On the dimension of twisted centralizer codes

S. P. Glasby, Cheryl E. Praeger, Adel Alahmadi

Given a field $F$ , a scalar $λ \in F$ and a matrix $A \in F^{n \times n}$ , the twisted centralizer code $C_{F} (A, λ) := {B \in F^{n \times n} ∣ A B - λ B A = 0}$ is a linear code of length $n^2…
