Abstract
In this paper, we consider a discrete version of Aleksandrov’s projection theorem. We prove that an origin-symmetric convex lattice set, whose lattice’s y-coordinates’ absolute values are not bigger than 2, can be uniquely determined by its lattice projection counts if its cardinality is not 11. This partly answers a question on the discrete version of Aleksandrov’s projection theorem which was proposed by Gardner, Gronchi and Zong in 2005.
