Kyureghyan (Universität Rostock) ; Arne Winterhof (Johann Radon Institute for Computational and Applied Mathematics (RICAM), Linz) %O Dissertation Universität Rostock 2024 %X We present a closed explicit formula for all generating polynomials of a very popular set of codes - the constacyclic codes over finite fields. This problem is equivalent to the factorization of the polynomial X^n-a into monic irreducible factors over a finite field for all positive integers n. From our explicit formula for this factorization we also derive the factorization of the n-th cyclotomic polynomial and of any composition of the form f(X^n) where f is an irreducible polynomial. Additionally, we present a construction of a large set of irreducible polynomials of the same degree. %L 510 %9 theses %9 Text %9 Hochschulschrift %R 10.18453/rosdok_id00004733 %U https://purl.uni-rostock.de/rosdok/id00004733 %U https://nbn-resolving.org/urn:nbn:de:gbv:28-rosdok_id00004733-8 %U https://d-nb.info/1356633250/34 %U https://doi.org/10.18453/rosdok_id00004733
