On a property of 2-dimensional integral Euclidean lattices
Eiichi Bannai, Tsuyoshi Miezaki
Let be any integral lattice in the 2-dimensional Euclidean space. Generalizing the earlier works of Hiroshi Maehara and others, we prove that for every integer , there is…

Nonexistence for extremal Type II $\ZZ_{2k}$-Codes
Tsuyoshi Miezaki
In this paper, we show that an extremal Type II $\ZZ_{2k}$-code of length dose not exist for all sufficiently large when .

An Upper Bound on the Minimum Weight of Type II $\ZZ_{2k}$-Codes
Masaaki Harada, Tsuyoshi Miezaki
In this paper, we give a new upper bound on the minimum Euclidean weight of Type II $\ZZ_{2k}$-codes and the concept of extremality for the Euclidean weights when . Toge…
