= Complete manifold
{wiki}

A (pseudo-)<Riemannian manifold> is geodesically complete when every inextendible affinely parametrized <geodesic> is defined for all real parameter values. In the positive-definite case, the <Hopf-Rinow theorem> identifies this with metric completeness. Null-only completeness in spacetime is a separate weaker condition.
