3. Lemmata in adic-rigid geometry.
This is an evolving set of learning notes on adic-rigid geometry.
(Doesn't seem evolving no more recently though.)

This is the expository notes for a non-trivial étale covering space of rigid projective line.
5. Very brief lectures
This is the lecture notes for lectures I gave at HKUST, invited by Huai-Liang Chang. It probably contains some minor mistakes, use at your own risk.
