| As we shall see below, this is not the case for algebraic fibring, unless a stronger notion of morphism between logics is adopted. |
| The concept of coding is based on the new notion of strong morphism between trace monoids. |
| A trace coding is an injective morphism between two trace monoids. |
| They also genotyped each participant using single nucleoptide poly morphism analysis of MC1R alleles. |
| The fact that each morphism has an inverse corresponds to the fact that identity is a symmetric relation. |
| A groupoid is a category in which every morphism is an isomorphism. |
