11. In the case of matrices, the bijection follows from resolvant formulas. 12. This is where the concept of a bijection comes in : define the correspondence 13. Normed spaces for which the map ? is a bijection are called reflexive. 14. The image of a computable set under a total computable bijection is computable. 15. There is thus an inclusion-reversing bijection between the projective spaces and. 16. Such a bijection can be obtained using the Pr�fer sequence of each tree. 17. Formally, the gluing is defined by a bijection between the two boundaries. 18. Because the isomorphism must be a bijection , every recursive model is countable. 19. While the map is an analytic bijection , its inverse is not continuous. 20. Since is a bijection , is an injection, and thus is isomorphic to.
