I have a question about an equation in Maggiore's Modern Introd. to Quantum Field Theory p.52:(adsbygoogle = window.adsbygoogle || []).push({});

[tex]\delta x^\mu = w^\mu_\nu x^\mu = \sum_{\rho < \sigma} A^\mu_{(\rho \sigma)} w^{\rho \sigma}[/tex]

where the A is defined as

[tex]A^\mu_{(\rho \sigma)}=\delta^{\mu}_{\rho}x_\sigma - \delta^\mu_\sigma x_\rho[/tex]

If I do this calculation I always end up with a factor 3 on the right hand side times the desired result. Is this an error in the book? Or am I doing something wrong?
