On polycyclic codes over 𝔽2(𝔽2 + v𝔽2)

In this paper, we study a structure of polycyclic codes over mixed alphabet [Formula: see text], where [Formula: see text]. We have presented the constructions of their generator polynomials. Furthermore, we examine the results on separability using the same. We also investigate their annihilator duals. Further, we study a class of self-orthogonal codes over [Formula: see text] with certain conditions placed on the generator polynomials. Some examples have also been given at the end.
