3. Lemmata in adic-rigid geometry.
This is a dead set of primitive learning notes on adic-rigid geometry.
4. Why are they NOT simply connected?
Expository notes for a non-trivial étale covering space of rigid projective line.
5. Very brief lectures
Lecture notes for lectures I gave at HKUST, invited by Huai-Liang Chang. It probably contains some minor mistakes, use at your own risk.
6. Example of unramified liftings of representations
This contains an example of a pair of unramified liftings of a representation (of a finite group) in positive characteristic, so that their geometric generic fibres are different (as representations of the finite group).
