Abstract

Let \(\theta \) be an automorphism on a finite field \(\mathbb {F}_q.\) In this paper, we give a way to construct and enumerate Euclidean self-dual \(\theta \)-cyclic codes of length n over \(\mathbb {F}_q\) when n is even and \(\gcd (n,|\theta |)=1.\) The restriction \(\gcd (n,|\theta |)=1\) implies that the \(\theta \)-cyclic codes are in fact cyclic codes and \(q=2^m,\) for some integer \(m\ge 1.\) The construction and enumeration are done by analyzing the orbits of cyclotomic cosets under a multiplier map induced by \(\theta .\)
