Chapter 216OptionalScaffold
Intrinsic Topology of the Universe
Prerequisites. Direct starred prerequisites: none. No later core chapter depends on this route.
Remark 216.1¶
Draft status. This chapter is a scaffold.
Opening obstruction
In constructive univalent foundations, maps out of a universe can satisfy continuity principles that have no classical set-theoretic analogue.
Development contract
Freeze the TypeTopology assumptions, construct the intrinsic topology and prove the selected continuity/Rice-style consequence. State function extensionality, convergence and universe hypotheses at every export.
