Define hermitian conjugate

WebA square complex matrix whose transpose is equal to the matrix with every entry replaced by its complex conjugate (denoted here with an overline) is called a self-adjoint matrix or a Hermitian matrix (equivalent to the matrix being equal to its conjugate transpose); that is, A is self-adjoint or Hermitian if \( {\bf A} = {\bf A}^{\ast} . WebDec 21, 2016 · The correct answer is: they're not, necessarily. There are two things that happen when you take the Hermitian conjugate: a transpose, and a complex conjugation. If you break down the Hermitian operators into symmetric and anti-symmetric parts, the symmetric part is real and the anti-symmetric part is imaginary.
