 Goulwen Fichou, Johannes Huisman: A geometric description of the neutral component of the
Jacobian of a real plane curve having many pseudolines,
Math. Nachr. 254255 (2003) 126131
Abstract:
A pseudoline of a real plane curve is a real branch
that is not homologically trivial in the real projective plane. A real plane curve
of degree d is said to have many pseudolines if it has
exactly d2 pseudolines and if its genus is equal to d2. We
present a planar description of the neutral component of the set of
real points of the Jacobian of such a curve. When the curve is defined
over Q, it gives rise to a planar description of a subgroup of
finite index of the MordellWeil group of the curve.
