What is the meaning of "Hermitian"? - Mathematics Stack Exchange
A Hermitian matrix is a matrix that is equal to its conjugate transpose. This generalizes the concept of a "symmetric matrix", since every real symmetric matrix is Hermitian. However, …
functional analysis - Distinguishing between symmetric, Hermitian …
In any reasonable sense, symmetric=hermitian=self-adjoint. For genuinely unbounded operators, symmetric does not imply self-adjoint, and, unless the thing is already self-adjoint, its adjoint is …
Why hermitian, after all? [duplicate] - Physics Stack Exchange
Jun 24, 2016 · Hermitian operators (or more correctly in the infinite dimensional case, self-adjoint operators) are used not because measurements must use real numbers, but rather because …
If $A,B$ are Hermitian and - Mathematics Stack Exchange
Sep 26, 2019 · Thanks! This makes more sense, I forgot A and B were also hermitian in this problem. I appreciate the additional elaboration.
linear algebra - Matrices which are both unitary and Hermitian ...
Hermitian matrices are precisely the matrices admitting a complete set of orthonormal eigenvectors such that the corresponding eigenvalues are real. So unitary Hermitian matrices …
If $AA^*=AA$, how to prove $A$ is an Hermitian? [duplicate]
Jul 23, 2015 · @OpenSeason Maybe quicker: any Hermitian matrix can be diagonalized. It's obvious for diagonal matrices..
Lie Algebra Conventions: Hermitian vs. anti-Hermitian
Mar 25, 2017 · and this binary operation is indeed skew-symmetric, billinear and fulfills the Jacobi identity, so one can indeed, at this abstract level, define a Lie algebra of Hermitian matrices.
linear algebra - Prove that Hermitian matrices are diagonalizable ...
Apr 16, 2013 · I am trying to prove that Hermitian Matrices are diagonalizable. I have already proven that Hermitian Matrices have real roots and any two eigenvectors associated with two …
Showing that Position and Momentum Operators are Hermitian
Nov 11, 2020 · Homework-like questions and check-my-work questions are considered off-topic here, particularly when asking about specific computations instead of underlying physics …
What is a basis for the space of $n\times n$ Hermitian matrices?
With entries strictly in $\mathbb {R}$, Hermitian matrices are just symmetric matrices so your basis is correct and is indeed the very one for symmetric matrices. However, the problem …
