In
algebraic geometry, the Barth–Nieto quintic is a
quintic
3-fold in 4 (or sometimes 5) dimensional
projective space studied by
Wolf Barth and Isidro Nieto (
1994) that is the
Hessian of the
Segre cubic.
Definition
The Barth–Nieto quintic is the closure of the set of points (x0:x1:x2:x3:x4:x5) of P5 satisfying the equations
Properties
The Barth–Nieto quintic is not
rational, but has a smooth model that is a modular
Calabi–Yau manifold with
Kodaira dimension zero. Furthermore, it is
birationally equivalent to a compactification of the
Siegel modular variety A1,3(2).
