本文对格多面体上的Minkowski赋值建立了一个完整的分类,它插入整数上的特殊线性群,并且是平移不变的。在逆变的情况下,唯一这样的估值是投影体的倍数。在等变的情况下,只有这样的估值是广义差体与新定义的离散斯坦纳点的倍数相结合。
A complete classification is established of Minkowski valuations on lattice polytopes that intertwine the special linear group over the integers and are translation invariant. In the contravariant case, the only such valuations are multiples of projection bodies. In the equivariant case, the only such valuations are generalized difference bodies combined with multiples of the newly defined discrete Steiner point.
