Author: archil archil.kipiani@
Keywords: mono-unary algebras, automorphisms group, cardinal number, continuum hipothesis
Annotation:

The characterization of all cardinal numbers that are cardinals of automorphism groups of mono-unary algebras is given. Connections are also established between notion of automorphism of mono-unary algebras and the continuum hypothesis.
