Dirac matrix

Dirac matrix

[di′rak ′mā‚triks]
(quantum mechanics)
Any one of four matrices, designated γμ(μ = 1, 2, 3, 4), each having four rows and four columns and satisfying γμγv+ γvγμ= δμ v , where δμ v is the Kronecker delta function, which matrices operate on the four-component wave function in the Dirac equation. Also known as gamma matrix.
