Constacyclic and Quasi-Twisted Hermitian Self-Dual Codes over Finite Fields

Ekkasit Sangwisut, Somphong Jitman, Patanee Udomkavanich

Constacyclic and quasi-twisted Hermitian self-dual codes over finite fields are studied. An algorithm for factorizing $x^n-\lambda$ over ${\mathbb{F}}_{q^2}$ is given, where $\lambda$ is a unit…
