A modern interpretation of the Dirac-electron continuity equation More formally, the expansion of the preceding determinant in (45) verifies that a symmetric matrix is obtained for [partial derivative][h.sub.i](P,k)/[partial derivative][P.sub.j] due to the commutation of second-order partial...
Notation δ(φ) indicates the Dirac function and it is defined as the derivative of the Heaviside function H(φ):H(z)={1,z≥00,z<0,δ(z)=ddzH(z)={0,z≠0+∞,z=0 In order to compute the partial differential equation in Eq. (4), discontinuous functions H(φ) and δ(φ)need...
here, the trace is a sum over both Dirac (Tr) and color () indicesFootnote 2 Also, the effective action (2.3) is equivalent to the following form (2.4) in which represents the n-point function of the non-Abelian gauge field with the minimal coupling to the fermionic matter. From a ...
