Title: Frames and locales: topology without points
Abstract: Motivation: geometric and other. What we perceive as points; can we do =
without them? A short outline of history.=20
Apologia for (further) generalizing the concept of space. What can be =
lost and what can be gained.
Classical concepts in new attire. Where the theory stays almost the same =
(HofmannLawson duality, more about spatiality) and where it is better =
(examples: paracompactness, closed subgoup theorem).
Enriched pointfree structures (uniformity, nearness, etc.); modelling =
approximation.
Surprise: constructivity of clasically nonconstructive facts. =
Constructive Tychonoff theorem, compactification and completion.
