KATAGIRI Yu

Non-archimedean analysis, non-archimedean functional analysis, distributions.

I study number theory, especially, non-archimedean analysis. Currently, I am interested in the p-adic Fourier theory, which describes the relation between p-adic distributions and some rigid analytic functions and has applications to construction of p-adic L – functions.

KUMABE Satoshi

Research interest: Number Theory, Hypergeometric functions

I study number theory. My research interests lie in analogous functions of hypergeometric functions on finite and p-adic fields and their applications to problems involving the zeta and L-functions of algebraic varieties. Moreover, I am a graduate of this program. Throughout the mathematical modeling course, I have also worked on a forest transition model via stochastic differential equations, which is still ongoing.

Plasma Science and Engineering • Plasma Applications

The 4th state of matter so-called plasma is an ionized gas that contains electrons, ions, atoms, molecules, and radicals. Plasma has been widely used in several applications including materials processing, medical, and agricultural. My research field is atmospheric pressure plasma for materials processing. Recently, I have been developing atmospheric pressure plasma for medical and agricultural applications as well as studying its electrical and physical properties. Also, I am interested in modeling and simulation of this plasma.

Cheng Yuzhong

Probability and Statistics, Deep Learning

My work sits at the intersection of probability theory, statistics, and deep learning. At the moment, I focus on statistical inference for stochastic differential equations (SDEs)—parameter estimation, high-frequency sampling, asymptotic theory. I am also interested in deep-learning-based estimation methods and limit theorems of interacting particle systems.
