June 2021 update for the “Kourovka Notebook (Unsolved Problems in Group Theory)”

An update for the current 19th edition of “Kourovka Notebook (Unsolved Problems in Group Theory)” is  posted.  A few new solutions and new references appear, both for problems from the latest section and from the previous ones. (But of course many problems remain very much open:-).)

Recall that “Kourovka Notebook” is a famous collection of open problems in group theory proposed by hundreds of mathematicians from all over the world, published every 2-4 years since 1965.

As an additional feature of the Kourovka Notebook, a new series of online seminars “Kourovka Forum” has been launched recently: http://mca.nsu.ru/kourovkaforum/ . Previous talks, with slides and recorded lectures, can be found at http://mca.nsu.ru/kourovkaforum/scheduleandabstracts/.
