报告题目:Recent progress on DDVV-type inequalities
报告人:葛建全教授 北京师范大学
报告摘要:Recently we generalize the known DDVV-type inequalities for real (skew-)symmetric and complex (skew-) Hermitian matrices into arbitrary real, complex and quaternionic matrices. Inspired by Erd\H{o}s-Mordell inequality, we establish DDVV-type inequalities for matrices in the subspaces spanned by a Clifford system or a Clifford algebra. We also generalize the B\”{o}ttcher-Wenzel inequality to quaternionic matrices. In this talk, we will briefly introduce the background, the new progress above, and some open questions.
