"Poankare-no Okurimono" by MINAMI Miyako and NAGASE Teruo

MINAMI Miyako and NAGASE Teruo are a couple, and both studied mathematics in their universities. After that MINAMI became a mathematical teacher, and NAGASE became a mathematical scholar. The most of this book is written by MINAMI, and the last part is written by NAGASE.

"This is a three-manifold which I realized. It vanishes one circles, but it is not topologically same as a three dimensional sphere."

With these words and a strange solid, Mr. Tachibana has left from Yayoi. So Yayoi began to understand the meaning... This book is a introduction to Poincare's conjecture. Now (in 2008) has the conjecture been solved? Maybe yes. But the publication of this book is 2001, and it has not been solved yet.
