Title of Presentation

“Joy and motivation of research in mathematics”

What is the charm of mathematics that attracts mathematicians? This is probably the question ordinary people have about mathematicians. Though people are not familiar with the objects of research in mathematics, they can still share the feeling mathematicians have toward them. There are common points in attitudes of researchers in other disciplines or even artists. A change of idea often brings a totally new view of a problem and sometime leads to the solution, which is a true joy of doing mathematics. In this talk, I will review my research life and explain about the joy and motivation of research in mathematics.
