DDVV-type inequality for Hermitian matrices
arXiv:1610.05020
Abstract
In this paper we extend DDVV-type inequalities involving the Frobenius norm of commutators from real symmetric and skew-symmetric matrices to Hermitian and skew-Hermitian matrices.
15 pages, accepted version, to appear in Linear Algebra and its Applications, more detailed proof of DDVV-type inequality by Ge-Tang's method is presented according to the referee's directive and helpful comments
