From 14 July to 18 July, Professor Yang Nanying of the School of Science of Jiangnan University (Wuxi, PRC) visited FM&IT to further strengthen scientific cooperation between the scientific schools of group class theory of Jiangnan University (Wuxi, PRC) and the scientific schools of the Faculty of Mathematics and Information Technologies of P.M. Masherov Vitebsk State University.

During Professor Yang Nanyin's stay at the Department of Mathematics of P.M. Masherov Vitebsk State University there were held seminar sessions on the problems of description of canonical subgroups in the theory of radical and coradical classes, at which the papers of Professors N.T. Vorobyov, Yang Nanyin and N.N. Vorobyov were presented for further participation in the large International Conference on Group Theory (Ekaterinburg, Russia, 21-27 July).

It should be noted that successful mutual effective cooperation between the scientific mathematical schools of P.M. Masherov VSU and Jiangnan University has been carried out for 12 years, which is confirmed by more than 13 joint publications of scientists of the schools in well-known international mathematical journals.
