Mathematical Sciences
The human activity in Mathematics has a long history since Greek ages, and is still developing itself. Mathematics can also serve as a basis of several other sciences, such as Physics, Chemistry, Biology, Computer Science, Engineering and Economics. Our course of mathematical science covers not only classical fields of mathematics (Algebra, Geometry, Analysis) but also applied fields such as Information mathematics and mathematical finance. Students are expected to acquire wide view and clear mind in mathematical science, which can be realized as activities of researchers, teachers and engineers in the future.

Mathematical Sciences
We research on various aspects of mathematical science. Main subjects are algebra such as number theory and representation theory, theory of topological groups and topological spaces, theory of differential equations, probability theory with applications to finance, applied mathematics such as numerical analysis and time series analysis.
