which has as parallel morphism the composition with coev l a at x n . Again, these morphisms factorize over the end, and by composing the defining equation (4.43) with the balancing of x we see that the block space is also the equalizer T fine , ( v ) ( ... x m x n y ) −→ T pre ( ... x m x n y ) producttext tildewidest hol x producttext (coev l ) productdisplay x integraldisplay a ∈A T pre ( ..., x m ( a a ) .x n y ) . (4.45) We use the latter description of the block space to show Lemma 4.19. The block functor depends on the choice of a starting point per disk only up to canonical coherent natural isomorphism. Proof. We define canonical natural isomorphisms Γ v ,v : T fine , ( v ) ( ..., x m x n y ) −→ T fine , ( v ) ( ..., x m x n y ) , (4.46) for each pair of starting points v,v per disk, that satisfy the coherence relation Γ v ′′ ,v Γ v ,v = Γ v ′′ ,v .
