题目：Constructions of complex equiangular lines

报告人:Jonathan Jedwab

（Simon Fraser University, Canada）

Abstract.  Equiangular lines in real space have been studied for more than 70 years. The study of equiangular lines in complex space was sparked by Zauner’s 1999 thesis on quantum designs, and there has been intense effort by mathematicians and physicists since then to determine the maximum number of equiangular lines in complex d-dimensional space. I shall survey the major results in this area and the techniques used to find them. I shall then suggest three possible new research directions involving other combinatorial structures.

This is joint work with Amy Wiebe.
