## Mathematics

Below are some notes I have written up for some courses I have taken or I gave. (Very Rough!)

- 2018-1 Geometric Analysis: Yamabe Problem and Geometric flow (Sogang University, Mathematics, Prof. Pak Tung Ho) / daily updated (last updated: 2018-06-08)
- 2017-1 General Relativity (Sogang University, Physics, Prof. Jeong-Hyuck Park) / revised (2019-02-08)

Also, these are some slide files that were presented in several classes and seminars.

The following notes are available upon request (incomplete note/not open to public)

- Introduction to Partial Differential Equation (written in Korean)
- Existence of forward self-similar solution of Navier-Stokes for large initial data (review note of the work of Jia-Sverak)
- Lectures on elliptic and parabolic equations on Holder spaces (based on the book of Krylov)
- Introduction to Random process (based on the book of Krylov)
- Littlewood-Paley theory and Kato-Ponce inequality (based on the paper of Dong Li, Fractional Leibniz rules and Kato-Ponce inequality)
- On the Cauchy problems for quasilinear PDEs (based on the lecture series given by Prof. Sung-Jin Oh)

## ${\rm \LaTeX{}}$

Below are lecture notes on LaTeX (usually written in Korean)
