20.500.12556/DKUM-93600 Bi-monotone maps on the set of all variance-covariance matrices with respect to minus partial order Let ▫$H^+_n({\mathbb R})$▫ be the cone of all positive semidefinite ▫$n \times n$▫ real matrices. We describe the form of all surjective maps on ▫$H^+_n({\mathbb R})$▫, ▫$n \ge 3$▫, that preserve the minus partial order in both directions. integer partition young diagram irreducible character immanant alternate matrix true false true Angleški jezik Angleški jezik Znanstveno delo 2025-07-05 03:07:23 2025-07-24 11:16:38 2025-09-01 09:12:26 0000-00-00 00:00:00 2025 0 0 str. 26-49 Vol. 705 Jan. 2025 0000-00-00 Zaloznikova NiDoloceno NiDoloceno 0000-00-00 0000-00-00 2025-01-15 517.9 218627331 10.1016/j.laa.2024.10.025 0024-3795 https://www.sciencedirect.com/science/article/pii/S0024379524004105?via%3Dihub 1 690f2227-593c-11f0-8a8e-00155d000105 https://dk.um.si/Dokument.php?lang=slv&id=193281 Ekonomsko-poslovna fakulteta 0 0 0
