SUMMARY:Семинар "Алгебра и логика"
DESCRIPTION:На 14 май 2021 г. (петък) от 13:00 часа ще се проведе дистанционно заседание на семинара “Алгебра и логика”. \nДоклад на тема \nNon-finitely based and limit varieties of algebraic systems\nще изнесе Веселин Дренски. \nРезюме. A variety of algebraic systems is non-finitely (or infinitely) based if it does not have a finite basis of identities. It is just-non-finitely based (or limit) if it is non-finitely based but all its proper subvarieties are finitely based. By the Zorn lemma every variety without a finite basis of identities contains a just-non-finitely based subvariety. \nWe survey results on non-finitely based varieties of groups\, semigroups and on associative\, Lie and nonassociative rings and algebras.\nWe also present examples of just-non-finitely based varieties of nonassociative algebras and varieties of pairs over fields of characteristic 0.\n  \nСеминарът ще се проведе посредством платформата Zoom и всеки желаещ може да се присъедини като последва линка: \nhttps://us02web.zoom.us/j/85137375021?pwd=RE5QczdFTE1xL1R6MnI2b1lkcGczQT09  \nTopic: Онлайн семинар на секция “Алгебра и логика”\nTime: May 14\, 2021 01:00 PM Sofia\nMeeting ID: 851 3737 5021\nPasscode: 035647\n  \nОт секция „Алгебра и логика” на ИМИ – БАН\nhttp://www.math.bas.bg/algebra/seminarAiL/\n============================== =====================
