Professor Ijiri is a Japanese professor at CMU, teaching accounting. I met him with Japanese students today.
He came to the
He had a wide knowledge out side of his accounting and talked about his recent interest about Four Color Problem, topology (one area of mathematics) and so on. Also, he stressed that multi-disciplinary areas are challenging to work on. He has started thinking about the combination of accounting and topology, though they seem to be in a different area. He was very impressive for me.
My theme is the combination of business and technology, and that is the reason I came to Carnegie Mellon. Especially, new Dean of Tepper emphasizes the combination, and that is a good sign for me.
Let me talk a little bit about For Color Problem Theorem. Briefly, the theorem is about the fact that any map can be colored by four colors. That fact was found in the 1860s and proved in the 1970s.
