Title: The classification of complete improper affine spheres with singularities of low total curvature and new examples
(Submitted on 25 Mar 2024)
Abstract: We classify complete improper affine spheres with singularities (say improper affine fronts) in unimodular affine three-space $\boldsymbol{R}^3$ whose total curvature is greater than or equal to $-8\pi$. We also study the asymptotic behavior of complete embedded ends of improper affine fronts. Moreover, we give new examples for this class of surfaces, including one which satisfies the equality condition of an Osserman-type inequality and is of positive genus.
