高校のときは(受験)数学があまり好きではなく、工学部へ。囲碁にハマっており自分より囲碁が強い人工知能を作りたかった。当時の人工知能はまだまだ卵の段階で魅力を見いだせず、機械に考えさせるのではなく、やはり自分が考えたいと思うようになり数学を学び始める。同時にサークル活動にて演劇をやっており、役者か学者か、迷った末に少しだけ学者のほうに才能を感じたので研究者を目指す道へ。とにかく面白いものが好きで、分野にこだわりはなく、正直に言うとそもそも学問でなくてもよい。大学院では3次元双曲幾何学、その後タイヒミュラー理論とそれに関連するランダムウォーク、現在は2次元と3次元の双曲幾何学をつなげる分野に興味を持っている。
In high school, I didn’t particularly enjoy mathematics, so I went on to study engineering. At that time, I was deeply into the game of Go and wanted to create an AI that could play better than I could. However, AI was still in its infancy, and I realized that I was more interested in thinking for myself than in making machines think. That realization led me to study mathematics. At the same time, I was also involved in a theater club, and for a while, I couldn’t decide whether to pursue acting or academia. In the end, I felt I had slightly more talent as a scholar than as an actor, so I chose the research path. I have always been drawn to whatever I find intellectually engaging, regardless of the field, and to be honest, it doesn’t even have to be “academic”. In graduate school, I studied 3-dimensional hyperbolic geometry; later, my interests expanded to Teichmüller theory and related random walks. Currently, I’m fascinated by questions that bridge 2- and 3-dimensional hyperbolic geometry.
2次元、3次元の双曲幾何に関してはさまざまな数値計算が可能であることが知られている。本講演では講演者の博士論文や、最近の研究における数値計算において関連する話題と合わせて紹介する。
A variety of numerical computations can be performed in two- and three-dimensional hyperbolic geometry. In this talk, I will talk about some computations done in my doctoral dissertation and recent research.
工学部など「数学科以外」の学部を卒業し、大学院から数学を始め、数学者として生きている人間は少数派である。大学院時代、ポスドク時代などに気をつけていたことなどについてお話する。
Those who graduated from faculties other than mathematics—such as engineering—and then began studying mathematics in graduate school to become mathematicians are in the minority. In this talk, I will share some thoughts on what I paid attention to during my graduate and postdoctoral years.
