| Outline of Research at the Start |
This project aims to study dense packings of congruent objects in the Euclidean space. The most important objects of interest are hyperspheres, whose packings give rise to error-correcting communication protocols which are widely employed today. Since different packings might lead to protocols differing in efficiency, reliability, and fitness for a given purpose, our aim is to find, in some sense, the best possible packings. The main tools we use is a family of highly symmetrical complex unit vectors.

| Outline of Annual Research Achievements |
6次の複素アダマール行列の構造特性を研究し、論文を書きました。島根大学で「Sets, Designs, and Graphs」といいう国際研究集会を開催しました(7月20-21日)。早稲田大学で「早稲田離散数理」といいう研究集会で距離集合に関する発表をしました(3月16日)。今後の研究に向けた準備を始めました。つまり、研究はおおむね順調に進展しています。
