U+22B9 "⊹" Hermitian Conjugate Matrix Unicode Character
Unicode Version 17.0
⊹
U+22B9 "⊹" Hermitian Conjugate Matrix is a mathematical symbol used in linear algebra and quantum mechanics to denote the conjugate transpose of a matrix, which is obtained by taking the transpose of the matrix and then applying complex conjugation to each entry. This operation, often represented by a superscript dagger or a small plus sign, is essential for defining Hermitian matrices and unitary operators, playing a critical role in describing physical observables and symmetry transformations in quantum theory. The symbol itself resembles a decorative star or a rotated plus sign and is distinct from other similar Unicode characters, providing a concise notation for this advanced mathematical concept.
