Colóquio de Matemática
Resumo: We give a geometric algorithm to add points in the Jacobian of a smooth plane quartic. This algorithm assumes an arithmetic condition, namely that there is a line (or better a tangent) that cuts the quartic in rational points only. We will show that if the quartic is defined over a finite field Fq with q large enough, this can always be achieved. We will also state some open problems related to flexes.
