Abstract
In this paper, complement-equivalent arithmetic Zariski pairs will be exhibited answering in the negative a question by Eyral-Oka on these curves and their groups. A complement-equivalent arithmetic Zariski pair is a pair of complex projective plane curves having Galois-conjugate equations in some number field whose complements are homeomorphic, but whose embeddings in $\mathbb{P}^2$ are not. Most of the known invariants used to detect Zariski pairs depend on the \'etale fundamental group. In the case of Galois-conjugate curves, their \'etale fundamental groups coincide. Braid monodromy factorization appears to be sensitive to the difference between \'etale fundamental groups and homeomorphism class of embeddings.
