View on Github →chore(CategoryTheory/Monoidal): define tensorLeft/Right as abbrev for curriedTensor (#24735)
In the study of commutation of tensor products with colimits, we may not be completely sure about phrasing the assumptions (as instances) in terms of tensorLeft X
(resp. tensorRight Y
) or in terms of (curriedTensor C).obj X
(resp. (curriedTensor C).flip.obj Y
), even though they are defeq, and we could have to introduce lemmas/instances to deduce properties of tensorLeft X
from that of (curriedTensor C).obj
and vice versa. By making tensorLeft
and tensorRight
abbreviations, this PR makes such issues disappear.
