Lunch will be provided after each talk.

The 9th KMGS will be held on June 2nd, Thursday, via Zoom and Gather Town.
We invite a speaker Kihoon Seong from the Dept. of Mathematical Sciences, KAIST.
The abstract of the talk is as follows.

Slot (PM 12:00~12:40)
[Speaker]  Kihoon Seong from the Dept. of Mathematical Sciences, KAIST, supervised by Prof. Soonsik Kwon.
[Title] Transport properties of Gibbs and Gaussian measures under the flow of Hamiltonian PDEs   
[Discipline] Analysis
[Abstract] Transport properties of Gibbs and Gaussian measures under different transformations have been studied in probability theory. In this talk, I will discuss the invariance and quasi-invariance of Gaussian type measures on functions/distributions under the flow of Hamiltonian PDEs.
[Language] Korean (English if it is requested)

The 8th KMGS will be held on May 26th, Thursday, via Zoom and Gather Town.
We invite two speakers, Jaehoon Lee from the Dept. of Mathematical Sciences, KAIST, and Hyukpyo Hong from the Dept. of Mathematical Sciences, KAIST and IBS Biomedical Mathematics Group (BIMAG).
The abstract of the talks are as follows.

1st slot (PM 12:00~12:20)
[Speaker] Jaehoon Lee (이재훈) from the Dept. of Mathematical Sciences, KAIST, supervised by Prof. Paul Jung (폴 정 교수님)
[Title] Spectrum of sparse random graphs and related problems
[Discipline] Probability
[Abstract]
Around early 2010, there was a huge success in understanding the spectrum of large random matrices, in other words, large random graphs. It was only for large but dense random graphs at first. However, as random matrix theory has been developed, there is some progress in sparse cases. In this short talk, I will review a series of results for spectral statistics of sparse random graphs and explain their implications.

2nd slot (PM 12:25~12:45)
[Speaker] Hyukpyo Hong (홍혁표) from the Dept. of Mathematical Sciences, KAIST and IBS Biomedical Mathematics Group (BIMAG), supervised by Prof. Jae Kyoung Kim (김재경 교수님)
[Title] Deriving Stationary distributions from an underlying graph structure 
[Discipline] Mathematical Biology
[Abstract]
Randomness of biochemical reactions is inherent in various biological systems, from DNA to organs and the human body. These stochastic dynamics are frequently modeled using a continuous-time Markov chain (CTMC). Its long-term behavior is described by a stationary distribution, corresponding to its deterministic counterpart called a steady state. Stationary distribution can be derived analytically only in limited systems such as linear or finite-state systems. In this talk, I will introduce a recent result by Anderson, Craciun, and Kurtz deriving stationary distribution from the underlying graph structure of a reaction network and how we can extend it. For those who are first told the word ‘Mathematical Biology,’ I will briefly introduce mathematical biology before going into the detailed topic.

The 7th KMGS will be held on May 19th, Thursday, via Zoom and Gather Town.
We invite a speaker Wonwoong Lee from Dept. of Mathematical Sciences, KAIST.
The abstract of the talk is as follows.

Slot (PM 12:00~12:40)
[Speaker] Wonwoong Lee (이원웅) from Dept. of Mathematical Sciences, KAIST, supervised by Prof. Bo-Hae Im (임보해 교수님)
[Title] Modular forms and transcendental questions
[Discipline] Number Theory
[Abstract]
Modular curves for Hecke congruence groups, or more generally, for Fuchsian groups of the first kind can be seen as the moduli spaces of the isomorphism classes of elliptic curves with torsion data in some sense. In this talk, I will introduce the notion of modular curves and modular forms. If time permits, I will also introduce their applications to some transcendental questions.

We invite a speaker Doosung Choi from Dept. of Mathematical Sciences, KAIST.
The abstract of the talk is as follows.

[Title] 해외 수학과 포닥 지원은 어떻게 하는가 / Finding a postdoc position
[Discipline] General Topic
[Abstract]
한국의 수학과 박사과정 대학원생이 해외로 포닥을 지원하는 방법에 대해 발표합니다. 기본적으로 포닥을 지원하기위해 필요한 서류인 CV, 추천서, 연구소개서, 강의소개서 등을 어떻게 준비하는 지에 대해 설명드립니다. 또한 미국과 유럽은 한국과 달리 후기로 뽑기 때문에 지원 시기 및 절차가 많이 다릅니다. 어느 시기에, 어디서, 그리고 누구에게서 포닥 포지션을 구할 수 있는 지에 대한 다방면의 정보를 공유합니다.

I will present how to apply for the abroad postdoc position. Basically, I will explain how to prepare the CV, recommendation letters, research statement, teaching statement, diversity statement, etc., which are necessary documents to apply postdoc. The timelines for the postdoc application of the universities in the U.S. and Europe are very different from Korean universities. I will share a variety of information about when, where, and who you can apply for the postdoc position.
