Question about usage of opposite category here

[edit]

In particular, it seems like is being described as the same category as but with a different (opposite) monoidal structure, rather than a monoidal structure on the opposite category of as described in Opposite (category theory), which is the much more customary definition of .

So, given a monoidal category, , are we saying that is of the form or is it of the form ?

A "natural isomorphism" would mean between two functors between the same categories, so it seems like this would mean that you'd want and a natural isomorphism between and .

I agree. I'm trying to work out if a few different characterisations are equal and the description given in the opening line is not exactly correct. The differences are subtle but it's best to be as exact as possible. I believe the natural isomorphism is from to as you say.
