Novotný, Miroslav Mono-unary algebras in the work of Czechoslovak mathematicians. (English) Zbl 0741.08001 Arch. Math., Brno 26, No. 2-3, 155-164 (1990). A mono-unary algebra is a pair \((A,f)\) where \(A\) is a set and \(f\) a mapping from \(A\) into \(A\). This article includes a survey of results obtained by Czechoslovak mathematicians in the area of mono-unary algebras. The investigation of mono-unary algebras in Czechoslovakia was stimulated by a problem of O. Borůvka, formulated in 1950, concerning commuting matrices. This problem led to the study of homomorphisms of mono-unary algebras.
