The IMI Colloquium in June   Date：Wednesday, 19 June 2013           16:45-17:45 lecture Place：Lecture Room L-1 (3F, IMI, Kyushu University) Speaker：Shigeki Matsutani               (Manager, Mathematical Engineering Dept. 3, Simulation & Analysis R&D Center, Canon Inc.)   Title：Mathematics in Manufacturing Industry   Abstract: In this talk, based on mathematical studies in the research and development of new devices and materials in Canon Inc., I show how mathematics plays important roles in manufacturing industry. As their examples, an electric conduction problem in terms of percolation theory, and a problem of computational method in computational fluid dynamics (CFD) are illustrated. On the studies of the conductivity as a percolation phenomenon, I mention that the industrial requirements to support a design of materials bring novel viewpoints and interesting mathematical facts to us. I will give some comments on relations of the studies to the current mathematical problems. On the studies of the computational method in CFD, I show also that primitive insights based on singularity theory and abstract description of the fluid dynamics in terms of diffeomorphism yield a novel algorithm to analyze behavior of liquid in ink-jet printers numerically. I also show some interesting notions that mathematics is useful in applied science, which are written in my book "Tales in Linear Algebra" (Japanese, to be published in the fall of 2013). Finally I state that the collaboration between university and industry are quite crucial in mathematical analysis even for manufacturing industry.   IMI Colloquium Report
