### Department of Mathematics

The Department of Mathematics, established in 1930, has approximately 40 academic staff, 150 undergraduate students (2nd–4th year), and 100 masters/doctoral graduate students. We host several international conferences with over 200 visitors every year. Our department covers a wide range of research areas — from theory-driven approaches that mainly seek to achieve theoretical sophistication to more empirically oriented approaches that employ computers for calculations on various phenomena. More specifically, our research fields include hyperplane arrangements, representation theory, differential geometry, singularity theory, partial differential equations, mathematical physics, chaos, probability theory, dynamical systems, and so on. We have published the Hokkaido Mathematical Journal since 1972 in collaboration with the Mathematics Library, which contains about 100,000 books and accepts about 350 titles of journals annually.

Our recent major achievements and participating programs are: (1) Japan Science and Technology Agency, Strategic Basic Research Programs (CREST), Research Area: Modeling Methods allied with Modern Mathematics, Project: Theory on mathematical modeling for spatio-temporal patterns arising in biology (Research Supervisor: Shin-Ichiro Ei), (2) Japan Science and Technology Agency, Strategic Basic Research Programs (CREST), Research Area: Technology for Computing Revolution for Society 5.0, Project: Optimization problems and their solutions with safe and secure quality validation based on mathematics (Research collaborator: Akira Sakai), (3) Promotion Office for Integrative Mathematics, (4)Hokkaido University Ambitious Leader’s Program, (5) Ph. Discover(A project of Graduate school of Science, Hokkaido University).
