General Formulation, φ'∈Rn(R4;Rn(R4),R), φ'α(x;φ,0)=φα(x), Ω'(Ω,ε)={x|∃y∈Ω,x=x'*(y;ε)}, x'∈R4(R4;R), x'μ(x;0)=xμ, Conclusion, If δI(φ)/δφα(x)=0 then: (∂/∂xμ)Tμ(x;φ)=0, (d/dt)Q(t;φ)=0 where: T∈R4(R4;Rn(R4)), Q∈R(R;Rn(R4)), Tμ(x;φ)=∂x'μ(x;ε)/∂ε|ε=0L(φ*(x);∂*φ*(x))+∂φ'α(x;φ,ε)/∂ε|ε=0∂L(φ*(x);∂*φ*(x))/∂[∂μφα(x)], Q(t;φ)=∫d3xT0(t,x;φ) d. Local Complex Field, Consider the special case: n=2, L(x;y)=Lc(z(x1,x2),z†(x1,x2);z(y01,y02),・・・,z(y31,y32);z†(y01,y02),・・・,z†(y31,y32)) where: x∈R2, y∈R4×2, Lc∈C(C10), Lc(a,a†;b,c,d,e;b†,c†,d†,e†)∈R, 1. Euler-Lagrange Equation, δI(φ)/δφα(x)=0⇔{∂Lc(φ(x),φ†(x);∂φ(x),∂φ†(x))/∂φ(x)-∂/∂xμ∂Lc(・・・・・)/∂[∂μφ(x)]=0, ∂Lc(φ(x),φ†(x);∂φ(x),∂φ†(x))/∂φ†(x)-∂/∂xμ∂Lc(・・・・・)/∂[∂μφ†(x)]=0 where: φ(x)=z(φ1(x),φ2(x))
