3 HERMITIAN MATRICES
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 … Meer weergeven Hermitian matrices are fundamental to quantum mechanics because they describe operators with necessarily real eigenvalues. An eigenvalue $${\displaystyle a}$$ of an operator Meer weergeven Additional facts related to Hermitian matrices include: • The sum of a square matrix and its conjugate transpose • The difference of a square … Meer weergeven • Complex symmetric matrix – Matrix equal to its transpose • Haynsworth inertia additivity formula – Counts positive, negative, and zero eigenvalues of a block partitioned Hermitian matrix • Hermitian form – Generalization of a bilinear form Meer weergeven Main diagonal values are real The entries on the main diagonal (top left to bottom right) of any Hermitian matrix are real. Only the main diagonal entries are necessarily real; Hermitian matrices can have … Meer weergeven In mathematics, for a given complex Hermitian matrix M and nonzero vector x, the Rayleigh quotient $${\displaystyle R(M,\mathbf {x} ),}$$ is defined as: For real matrices and vectors, the condition of being Hermitian reduces to that of being … Meer weergeven • "Hermitian matrix", Encyclopedia of Mathematics, EMS Press, 2001 [1994] • Visualizing Hermitian Matrix as An Ellipse with Dr. Geo, by Chao-Kuei Hung from Chaoyang University, gives a more geometric explanation. Meer weergeven WebIf moreover, the problem matrix A is positive definite, then a new convergence bound is proved that depends only on how well H preconditions the Hermitian part of A, and on how non-Hermitian A is. In particular, if a scalable preconditioner is known for the Hermitian part of A, then the proposed method is also scalable.
