New 20-th edition of the “Kourovka Notebook (Unsolved Problems in Group Theory)”

“Kourovka Notebook” is a famous collection of open problems in group theory proposed by hundreds of mathematicians from all over the world. It has been published every 2-4 years since 1965. The latest 20th edition (editors Evgeny Khukhro and Victor Mazurov) has just been published, which contains 126 new problems and a number of comments on problems from the previous editions. Perhaps the most striking illustration of the success of “Kourovka Notebook” is the fact that more than 3/4 of the problems from the first issue have now been solved!

The new edition (now also on a dedicated web-site) is sponsored by School of Mathematics and Physics of the University of Lincoln and Sobolev Institute of Mathematics, Novosibirsk.
