View on Github →refactor(Order/OmegaCompletePartialOrder): Unify concepts of Scott Continuity (#13201)
We currently have two related but different concepts of Scott Continuity in Mathlib - ScottContinuous
in Order/Bounds/Basic
and OmegaCompletePartialOrder.Continuous'
in Order/OmegaCompletePartialOrder
. We previously showed (#6831) that ScottContinuous
implies OmegaCompletePartialOrder.Continuous'
(in general the converse isn't true).
This PR gives a more general definition of Scott Continuity, ScottContinuousOn
which specialises to ScottContinuous
and something equivalent to OmegaCompletePartialOrder.Continuous'
to give a more satisfactory unification of the concepts.
