How to raise and lower indices of gamma matrix in curved spacetime? Do we raise and lower the index of gamma matrix with $ g_{\mu \nu} $?


Gamma matrices with flat (curved) indices are raised & lowered with the flat (curved) metric, respectively.

    $\begingroup$ Yes. One should then multiply with the vielbein (or its inverse). $\endgroup$ – Qmechanic Jul 3 '18 at 8:55
