I am not researching now but I am studying about nonlinear partial differential equations. Partial differential equations are differential equations that contain partial derivatives of an unknown function. Since nonlinear partial differential equations cannot be generally solved, one tries to find a weak solution and approximate it. Now I am studying a viscosity solution which is one of the weak solutions.

I am interested in analytical fields such as differentiation and integration since high school student, and I wanted to study analytics at a university. It was just chance that I decided to study this field. I heard from Professor Koike about an approach of solving partial differential equations during seminar assignment, and felt that the way of thinking is very interesting. Thus, I am studying it with great interest.

I would like you to say what you want to learn at a university with confidence. When I decided to go on to mathematics department, I was not able to say anything to various people, saying, "After going to mathematics department, what will you be in the future?”. I will not go on to graduate school and I will be a mathematical specialist named actuary from the next spring. I will aim to acquire the qualification while working. It was not until I entered college that I knew actuary. I went on to mathematics department to satisfy my intellectual curiosity, and I have found what I want to do during college life. I think that some people may not have confidence in what they want to do because of a warry about the future. However, if you get to know a lot of values and knowledge during the college life, you could find the direction you'll take. Please proceed to the way to go with hope.
