  Recently a significant interest in ferromagnetic curved thin films has
appeared. In particular, thin spherical shells are currently of great interest
due to their capability to support skyrmion solutions which can be stabilized
by curvature effects only, in contrast to the planar case where the
Dzyaloshinskii-Moriya interaction is required. This paper aims to a
$\Gamma$-asymptotic analysis of the micromagnetic energy functional, when the
shell is generated, like in the case of a sphere, by a bounded, convex and
smooth surface.
