SUMMARY:Семинар "Алгебра и логика"
DESCRIPTION:На 1 декември 2023 г. (петък) от 13:00 часа ще се проведе хибридно заседание (присъствено в зала 578 на ИМИ-БАН и онлайн чрез платформата zoom) на семинара по „Алгебра и логика”. \nДоклад на тема: \nCharacterization of Ideals of Q-algebras Related to its G-part\nще изнесе \nдоц. Йорг Копиц\, ИМИ – БАН. \nАбстракт. In this presentation\, we study the \(G\)-part of \(Q\)-algebras \(X\)\, i.e. the set \(G(X)=\{x\in X:0x=x\}\). We show that \(G(X)\) is an abelian group\, whenever \(G(X)\) is an ideal and characterize all \(Q\)-algebras \(X\) such that \(G(X)\) is an ideal of \(X\). Moreover\, we show that\, up to isomorphism\, there is only one \(Q\)-algebra \(X\) with \(G(X)=X\)\, which is only possible if \(|X|=2^{k}\) (\(k\in \mathbb{N}\)). \nЛинк към Zoom-стаята на семинара:\nhttps://us02web.zoom.us/j/85137375021?pwd=RE5QczdFTE1xL1R6MnI2b1lkcGczQT09 \n\n\n\nОт секция „Алгебра и логика” на ИМИ – БАН\nhttp://www.math.bas.bg/algebra/seminarAiL/\n============================== =====================
