# Non-abelian Local Gauge Invariance in Field Theories

These are notes I made when I was studying the subject 20 years ago. They seem fine considering that I was student then. I believe they can be useful for those who are studying Yang-Mills and other related material.

Thanks, Sam!

nice,but looks some tough as it starts with non abelian lie group directly!

Some corrections:
The notes were originally made using Math-Type, then converted to LaTex. This caused some problems with the references to equations numbers. I corrected most of them but missed the followings:

1) on page 7, the sentence before Eq(3.20) should say "using $Eq(3.1)$ and $Eq(3.19)$"
2) on page 9 the sentence after Eq(3.35) should read "Adding $Eq(3.34)$ to $Eq(3.35)$".
3) on page 10 again you see a reference to $Eq(10)$, this should changed to $Eq(3.1)$.
4) on page 11 reference to $Eq(59)$ is made. The correct equation number is $Eq(4.13)$.
I think that is all. Please do tell me if you find some more of these.
