Abstract
We discuss models for massless Dirac fermions being subjected to a perpendicular magnetic field in spherical geometry. These models are analogs of Haldane's spherical construction for massful charge carriers. The single-particle states constructed here are easily implemented in existing numerical code for many-body problems in conventional quantum Hall systems. Moreover, the many-body states of fully filled sublevels in the subspace of lowest Landau-level index are skyrmions with respect to the layer spin.
