### Introduction to Department of Mathematics

Mathematics has long played important roles in the foundations of natural science. It strongly influences developments in technology and vice versa. Recent rapid technological innovations also reveal the importance of mathematics. For example, a mathematical idea to avoid interference provides us a secure chat through mobile phones. In our department, we have four main fields, namely, algebra, geometry, analysis, and information mathematics. The boundaries among these are not at all fixed and each area is prompting the others into further mutual development. Also some of the most profound developments arise on the boundaries of mathematics, physics, economics, computer science and so on. The administration and education of our department are jointly run by two formally different organizations in Niigata University, the Department of Mathematics of the Faculty of Science and the Graduate School of Science and Technology.
