20.500.12556/RUL-156331 Isotropy groups of the action of orthogonal $^\ast$congruence on Hermitian matrices We present a procedure which enables the computation and the description of structures of isotropy subgroups of the group of complex orthogonal matrices with respect to the action of $^\ast$congruence on Hermitian matrices. A key ingredient in our proof is an algorithm giving solutions of a certain rectangular block (complex-alternating) upper triangular Toeplitz matrix equation. isotropy groups matrix equations complex orthogonal matrices Hermitian matrices Toeplitz matrices izotropne grupe matrične enačbe kompleksne ortogonalne matrike hermitske matrike Toeplitzove matrike true false true Angleški jezik Slovenski jezik Članek v reviji 2024-05-20 13:58:19 2024-05-20 13:58:21 2024-08-30 09:16:26 0000-00-00 00:00:00 2024 0 0 Str. 101-135 Vol. 694 Aug. 2024 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 512.64 0024-3795 10.1016/j.laa.2024.04.013 194458115 1-s2.0-S0024379524001678-main.pdf 1-s2.0-S0024379524001678-main.pdf 1 5315F393CCBD1383FEFE744D40934369 9602aed275de79e1151cfb098cb04885fc6b326ead467d7eea5a6891102aab76 b0def32a-16a0-11ef-b600-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=183734 https://www.sciencedirect.com/science/article/pii/S0024379524001678 1 405b0b7c-16a0-11ef-b600-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=183733 Pedagoška fakulteta 0 0 0
