| 1. | In category theory, there are covariant functors and contravariant functors.
|
| 2. | In particular, ( covariant ) representable functors preserve all limits.
|
| 3. | See also gauge covariant derivative for a treatment oriented to physics.
|
| 4. | Another of Deser's research interests is covariant quantum gravity.
|
| 5. | The covariant derivative can in turn be recovered from parallel transport.
|
| 6. | The synchronous coordinate condition is neither generally covariant nor Lorentz covariant.
|
| 7. | The synchronous coordinate condition is neither generally covariant nor Lorentz covariant.
|
| 8. | The contravariant and covariant components of these vectors may be related by
|
| 9. | General covariant transformations constitute a subgroup of holonomic automorphisms of FX.
|
| 10. | Similar remarks apply to the colimit functor ( which is covariant ).
