41. It turns out that all of these descriptions uniquely determine the initial frame morphism . 42. A ( function considered merely as a morphism of addition between the underlying groups. 43. The map is then a bundle morphism covering. 44. The existence of this morphism is a consequence of the universal property which equality. 45. The term isomorphism literally means sameness ( iso ) of form ( morphism ). 46. This contraction morphism is sometimes called a blowup. 47. In category theory, this statement is used as the definition of an inverse morphism . 48. The partially ordered groups, together with this notion of morphism , form a category. 49. Notice that we did not use the gluing axiom in defining a morphism of sheaves. 50. Let be a morphism of Heyting algebras.
