Chajda, I. (ed.) et al., Contributions to general algebra 11. Proceedings of the Olomouc workshop ’98 on general algebra, “56. Arbeitstagung Allgemeine Algebra”, Olomouc, Czech Republic, June 12–14, 1998 and of the summer school ’98 on universal algebra and ordered sets, Velké Karlovice, Czech Republic, August 31–September 5, 1998. Klagenfurt: Verlag Johannes Heyn. 101-103 (1999).
It is proved that any directed colimit of copies of finite algebras \(A_1,\dots,A_n\), \(n\in\mathbb N\), is isomorphic to a retract of some \(A_i\), \(i=1,\dots,n\).
For the entire collection see [Zbl 0914.00059].
