View on Github →feat(data/equiv/basic): add a computable version of equiv.set.range (#6821)
If a left-inverse of f
is known, it can be used to construct the equiv both computably and with control over definitional reduction.
This adds the definition equiv.set.range_of_left_inverse
to mirror linear_equiv.of_left_inverse
and ring_equiv.of_left_inverse
.
