KIAS Horizon (webzine)
Somewhat obsolete parts of this website:
[myresearch] : This is supposed to be an informal research statement for my research, but I never really updated..
[hosted] : This lists some lecture series I hosted while I was at KIAS, with the links to the lecture videos. Unfortunately, KIAS stopped servicing the recorded videos (what a shame!) at some point, so this webpage is not much of use anymore.
Nice videos
for the paper "Quantum geometry of moduli spaces of local systems and representation theory" by A.B. Goncharov and L. Shen, arXiv:1904.10491
lecture videos by A. B. Goncharov, at IHES : [1] [2] [3] [4]
a very nice introduction to Fock-Goncharov-Shen's moduli spaces, quantization, and representation theory, which are related to much of my own research

James Simons - Origin of Chern-Simons (2011-Jul-28)
https://www.youtube.com/watch?v=8VipIKLg6-k

I think I learned something..Pierrick Bousseau - 10/1/2020 - Skein algebras from higher genus mirror symmetry (2020-Oct-1)
https://www.youtube.com/watch?v=wvbDET7nffg
about paper 2009.02266. This is where the positivity of the bracelets bases of the Kauffman bracket skein algebras of 4-punctured sphere and of once-punctured torus is proved for the first time in the literature. Used the scattering diagrams and broken lines (i.e. mirror symmetry), but seems quite different to me from Davison-Mandel (and Gross-Hacking-Keel-Kontsevich)Sean Keel - Mirror Symmetry Made Easy (2012-May-15)
https://www.youtube.com/watch?v=CldVBxgp67o
about Gross-Hacking-Keel's work. theta functions etc. I think I learned something by this video..

Canonical coordinates for Calabi Yau manifolds I - Sean Keel (2017-Mar-2)
https://www.youtube.com/watch?v=ibsc1fyEYXg
Great (introductory) talk for log CY.. I should watch it again..
(part of Workshop on Homological Mirror Symmetry: Methods and Structures (https://www.youtube.com/playlist?list=PLdDZb3TwJPZ4tU6XoRDGyI22qAsvYMVmh))Canonical coordinates for Calabi Yau manifolds II - Sean Keel (2017-Mar-4)
https://www.youtube.com/watch?v=okvHL2SoJTg
Continuation of the above. This one requires more algebraic geometry, hence harder for me to understand. But this one includes some reason why Keel was interested in mirror symmetry in the first place, and suggests some good problem(s).

near the end, he presented a statement that I was kind of looking for..

title is "Quantum theta bases for quantum cluster algebras". talk about his work with Davison. Quite elementary (and introductory) explanations. Great talk! Not so much into details, but he points out some crucial points of his work. Good to get a bird's-eye view.
