I would like to know how, given a metric with non-zero off-diagonal components [tex]g_{mn}, m \neq n[/tex], one can find if another (orthonormal or null) frame exists in which [tex]g_{\mu \nu}=constant[/tex] for all components of the metric. And if it exists how to compute this basis. Thanks!(adsbygoogle = window.adsbygoogle || []).push({});
