The structure of sets with cube-avoiding sumsets
Thomas Karam, Peter Keevash
We prove that if is an integer, is a finite abelian group, is a subset of not contained in any strict coset in , and are dense subsets of…

Additive Bases: Change of Domain
Boris Bukh, Peter van Hintum, Peter Keevash
We consider two questions of Ruzsa on how the minimum size of an additive basis of a given set depends on the domain of . To state these questions, for an abelian group…

Robot Positioning Using Torus Packing for Multisets
Chung Shue Chen, Peter Keevash, Sean Kennedy +2
We consider the design of a positioning system where a robot determines its position from local observations. This is a well-studied problem of considerable practical importance an…
