J. Matrix Anal. Appl., 27 (2005): 665-674]. As applications, we present some new bounds for determinants of original matrices and estimations for eigenvalues of Schur complement. By theoretical analysis, we improve the bounds of determinants established in Huang [Comput. Math. Appl., 50 (2005): 1677-1684]. }, issn = {1746-7659}, doi = {https://doi.org/2024-JICS-22713}, url = {https://global-sci.com/article/87445/an-improvement-on-disc-separation-of-the-schur-complement-and-bounds} }
