The monoidal comparison of the fibre functor #
Deligne's ω sends an object to the realization of its free
module, so its monoidal comparison is the comparison map of
(2.11.1) at two free modules, followed by the identification of the
relative tensor of two free modules with the free module of the
tensor product. On the generators of the tensor product of super
modules the composite has a completely explicit form: tensor the
two morphisms and shuffle. No coequalizer survives in that
formula, which is what makes the coherence of ω a computation in
the ambient category alone.

Instances For
The monoidal comparison on even-even generators.
The monoidal comparison on odd-odd generators.
The monoidal comparison on even-odd generators.
The monoidal comparison on odd-even generators.
The monoidal comparison is invertible as soon as the comparison map of (2.11.1) is.
