Abstract

The Kodaira dimension of a nondegenerate toric hypersurface can be computed from the dimension of the Fine interior of its Newton polytope according to recent work of Victor Batyrev, where the Fine interior of the Newton polytope is the subpolytope consisting of all points which have an integral distance of at least 11 to all integral supporting hyperplanes. In particular, if we have a Fine interior of codimension 11, then the hypersurface is of general type and the Newton polytope has lattice width 22. In this article we study this situation for lattice 33-polytopes and the corresponding surfaces of general type. In particular, we classify all 22-dimensional Fine interiors of those lattice 33-polytopes which have at most 4040 interior lattice points, thus obtaining many examples of surfaces of general type and genus at most 4040.
