摘要：
We prove a lower bound of Omega(d(3/2) . (2/root 3)d) on the kissing number in dimension d. This improves the classical lower bound of Chabauty, Shannon, and Wyner by a linear factor in the dimension. We obtain a similar linear factor improvement to the best known lower bound on the maximal size of a spherical code of acute angle theta in high dimensions. (C) 2018 Elsevier Inc.
