Názov: Half-Cyclic, Dihedral and Half-Dihedral Codes
Termín: 28.2.2020, 11:00 hod., M/213
In our talk, we discuss, in elementary terms, linear codes over Z_2 which are a generalization of the well-known cyclic codes and which are closed under 2-step cyclic shifts. We classify them in terms of special linear combinations of polynomials. Codes which are preserved under order-reversing automorphisms are also discussed, and a classification result in terms of special linear combinations of polynomials is obtained.
