We know the Yang-Mills theory Equation of Motion (eom) without source
∗D∗F=∗(d(∗F)+[A,(∗F)])=0.
My question is that what are the most simple form we can boil down this eom to its minimal?
∗(d(∗(dA+A∧A))+[A,(∗(dA+A∧A))])
=∗d∗dA+∗d∗(A∧A)+A(∗(da+A∧A))−(∗(dA+A∧A))A=0
This is what I get. How can we massage it further in order to make it as simple as possible but similar to the Maxwell's ---
∗d∗dA+...=0?
What is the simplest form of ... term?
p.s. What I got so far is that
... term is
C=∗d∗(A∧A)+A(∗(da+A∧A))−(∗(dA+A∧A))A. Do we have better way to simplify this complicated C in terms of A?
