WebThe determinant of a Hermitian matrix is real. The inverse of a Hermitian matrix is Hermitian as well. Conjugate of a Hermitian matrix is also Hermitian. If A is Hermitian, then A*A and AA* is also Hermitian. Any square matrix can be represented as A + iB, where A and B are Hermitian matrices. WebDec 3, 2024 · The determinant is obtained by performing various addition and and multiplication operations on its entries. Since complex conjugation can be done before or after these operations, your claim det A ¯ = det A ¯ holds. Regarding your last sentence, note also that transposing a matrix does not change its determinant.
