QFT 3 : Problem Set 2
1.) Peskin & Schroeder 16.1 Arnowitt-Fickler gauge
In this problem we are supposed to look at the Faddeev-Popov (FP) quantization of Yang-Mills (YM)
theory in the Arnowitt-Fickle

1.) Peskin & Schroeder 15.1
(a.)
The basis for the fundamental representation of SU(N) is formed by N N traceless Hermitian matrices.
The number of such matrices is = N 2 1.
