Definition
A bimorphism is a morphism or arrow in a category [ilmath]\mathscr{C} [/ilmath][1]:
- [ilmath]\xymatrix{ A \ar[r]^f & B} [/ilmath]
That is
Warning:A bimorphism need not be an isomorphism, when all bimorphisms in [ilmath]\mathscr{C} [/ilmath] are isomorphisms however, we say that [ilmath]\mathscr{C} [/ilmath] is balanced
