  We study the discrete energy spectrum of curved graphene sheets in the
presence of a magnetic field. The shifting of the Landau levels is determined
for complex and realistic geometries of curved graphene sheets. The energy
levels follow a similar square root dependence on the energy quantum number as
for rippled and flat graphene sheets. The Landau levels are shifted towards
lower energies proportionally to the average deformation and the effect is
larger compared to a simple uni-axially rippled geometry. Furthermore, the
resistivity of wrinkled graphene sheets is calculated for different average
space curvatures and shown to obey a linear relation. The study is carried out
with a quantum lattice Boltzmann method, solving the Dirac equation on curved
manifolds.
