Triangular curves and cyclotomic Zariski tuples
Resumen: The purpose of this paper is to exhibit infinite families of conjugate projective curves in a number field whose complement have the same abelian fundamental group, but are non-homeomorphic. In particular, for any d=4 we find Zariski (¿d2¿+1)-tuples parametrized by the d-roots of unity up to complex conjugation. As a consequence, for any divisor m of d, m¿1,2,3,4,6, we find arithmetic Zariski ¿(m)2-tuples with coefficients in the corresponding cyclotomic field. These curves have abelian fundamental group and they are distinguished using a linking invariant.
