A proof of purely singular splitting conjecture

Ka Hin Leung, Tao Zhang

A set $M$ of nonzero integers is said to split a finite abelian group $G$ if there exists a subset $S \subseteq G$ such that $M \cdot S = G ∖ {0}$ . Such a splitting is called…

On lattice tilings of $Z^{n}$ by limited magnitude error balls $B (n, 2, k_{1}, k_{2})$ with $k_{1} > k_{2}$

Ka Hin Leung, Ran Tao, Daohua Wang +1

Lattice tilings of $Z^{n}$ by limited-magnitude error balls correspond to linear perfect codes under such error models and play a crucial role in flash memory applications.…
