On the Strongly Hopfian Acts over Semigroups: 《Applied Mathematics》2025年第2期183-189,共7页Ksenya Anatolyevna Kolesnikova Igor Borisovich Kozhukhov; We find the necessary and sufficient conditions on a coproduct of connected acts over a semigroup to be strongly hopfian. From this, we deduce the conditions of the strong hopfness for unitary acts over groups. Moreov...; 关键词：Act Over Semigroup Act Over Group Strongly Hopfian Act
