Семинар “Алгебра и логика”
ZoomНа 13 май 2022 г. (петък) от 13:00 ч. ще се проведе дистанционно заседание на семинара по „Алгебра и логика”. Доклад на тема: A counterexample to the modular isomorphism problem ще изнесе Diego García-Lucas (Universidad de Murcia, Spain). Абстракт. The modular isomorphism problem asks whether the isomorphism type of the modular group algebra of a p-group G over a field of characteristic p determines the isomorphism type of G. It was explicitly mentioned in a survey by Richard Brauer in 1963, and was the only classical version of the isomorphism problem for group rings which had resisted a solution, though it received considerable attention. Several partial positive solutions were obtained imposing very strong conditions on the group G, for instance the one of being [...]
