SUMMARY
An inertial frame in General Relativity (GR) is mathematically defined as a basis in the tangent space. It is not necessarily induced by a coordinate chart; however, local coordinates can be established that induce this basis at a single point. These specific local coordinates are referred to as normal coordinates, which facilitate the analysis of physical phenomena in the vicinity of that point.
