| 11. | There are seven non-isomorphic solutions to the schoolgirl problem.
|
| 12. | In the previous example ( written in isomorphic to a list.
|
| 13. | Their fundamental groups are isomorphic because each space is simply connected.
|
| 14. | Note that the natural numbers are isomorphic to lists of units.
|
| 15. | Equivalently, they are birationally equivalent if their function fields are isomorphic.
|
| 16. | Furthermore, this space is isometrically isomorphic to its bidual.
|
| 17. | This is naturally isomorphic to the space of oriented straight lines in.
|
| 18. | To take another example, radii of curvature have isomorphic automorphism groups.
|
| 19. | This subgroup is discrete and isomorphic to \ mathbb { Z }.
|
| 20. | This lattice is isomorphic to the lattice of Hurwitz quaternions.
