| 11. | The work on relativistic fields with arbitrary spins was later important in supergravity.
|
| 12. | Such a theory is called a supergravity theory.
|
| 13. | Superstring theories, and eleven-dimensional supergravity.
|
| 14. | As usual, there is a supergravity supermultiplet.
|
| 15. | She is the author of many papers on black hole solutions in supergravity theories.
|
| 16. | At low energies, the superstring theories are approximated by supergravity in ten spacetime dimensions.
|
| 17. | Similarly, M-theory is approximated at low energies by supergravity in eleven dimensions.
|
| 18. | Supergravity is more restrictive because it places an upper limit on the number of dimensions.
|
| 19. | The supergravity theories that have attracted the most interest contain no spins higher than two.
|
| 20. | In 11d supergravity or M-theory, we have a 3-form electrodynamics.
