Organic Opals: Properties and Applicationse abelian groups and composition is bilinear), all finite limits and colimits exist, and these limits — especially kernel and cokernel — are well behaved. This leads to a set of axioms describing an “abelian” category. The axioms suffice to prove all the facts about commuting diagrams and connecting

Hans van Ditmarsch,Barteld Kooiprincipal result for these categories was a “coherence” theorem: If a certain pentagonal diagram (§VII.1.5) in . commutes, then all diagrams involving this . must commute. We now consider various extensions of this result.
