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).
