Abstract

Mathematics Mathematics, Applied Physical Sciences Science & Technology
Hartfiel's determinant inequality, first proved for two positive definite matrices, has been recently extended to the case of sector matrices by Lin, Hou and Dong. This paper contributes an improvement of Lin's result with a simple argument, we also present a complement of Hou and Dong's result. (C) 2019 Elsevier Inc. All rights reserved.
