In mathematics, a Hermitian matrix (or self-adjoint matrix) is a complex square matrix that is equal to its own conjugate transpose—that is, the element in the i-th row and j-th column is equal to the complex conjugate of the element in the j-th row and i-th column, for all indices i and j: or in matrix … Zobacz więcej Hermitian matrices are fundamental to quantum mechanics because they describe operators with necessarily real eigenvalues.

Hermitian matrix - Wikipedia
WitrynaA Hermitian matrix is a matrix that is equal to its tranconjugate, that is to the complex-conjugate of its transpose matrix. In order to speak about a Hermitian operator, one has to be in a complex vector space E with a Hermitian inner product ⋅, ⋅ on it. Then a linear map f from E to itself is Hermitian if it is equal to its adjoint, that ...

WitrynaBasics of Hermitian Geometry 8.1 Sesquilinear Forms, Hermitian Forms, Hermitian Spaces, Pre-Hilbert Spaces In this chapter, we generalize the basic results of Eu-clidean geometry presented in Chapter 6 to vector spaces over the complex numbers. Some complications arise, due to complex conjugation. Recall that for any complex number … Witryna如方块矩阵A的共轭转置A * 也是其负数，則A是斜許密矩阵或反許密矩阵（英語： skew-Hermitian matrix、anti-Hermitian matrix ）： . A * = −A. 或者，如A = (a i,j)： , =, 对 … WitrynaThat is, we can view the Hermitian form on v 1,v2 in terms of the (E-linearly extended) symplectic form applied to v 1 2V and v2 2V¯ in RHS(II.E.6). Unitary groups. Henceforth we assume that our Hermitian form H is nondegen-erate, which makes B00(and B0) nondegenerate by (II.E.8).
