关于最大指数为2的格
On lattices of maximal index two
摘要:
n维欧氏格L的最大指数是L的n个独立极小向量所张成的子格的最大指数。本文证明了最大指数为2的完美格的维数不超过5。
英文摘要:
The maximal index of a Euclidean lattice L of dimension n is the maximal index of the sub-lattices of L spanned by n independent minimal vectors of L. In this paper, we prove that a perfect lattice of maximal index two not provided by a cross-section has dimension at most 5.
