讲座内容：

Cut locus is defined by Poincare in the beginning of 20 century, and studied long time in global differential geometry. In my talk, we will review its history and recent results, a generalization of Jacobi’s last statements, and several topics.

“Intuitive geometry” is the title of book written by Hilbert and Cohn-Vossen in the first half of 20 century.
