Studying the life of Sonya Kovalevskaya, we visited her home estate Polybino where we have an interesting talk with the Museum  of Sonya Kovalevskaya director.

In Minsk we met with outstanding mathematicians and historians.

The trip to Stockholm University and the Mittag-Leffler Institute was very productive too.

Here we met those who preserve the memory of Sophia Kovalevskaya in Sweden. For example, Jan Eric Björk has created beautiful sculptures of "Professor Sonya" and has published a few books about Kovalevskaya.
