A note on universal minimal dynamical systems

Sławomir Turek (1991)

Commentationes Mathematicae Universitatis Carolinae

Similarity:

Let M ( G ) denote the phase space of the universal minimal dynamical system for a group G . Our aim is to show that M ( G ) is homeomorphic to the absolute of D 2 ω , whenever G is a countable Abelian group.

A remark on supra-additive and supra-multiplicative operators on C ( X )

Zafer Ercan (2007)

Similarity:

M. Radulescu proved the following result: Let X be a compact Hausdorff topological space and π C ( X ) C ( X ) a supra-additive and supra-multiplicative operator. Then π is linear and multiplicative. We generalize this result to arbitrary topological spaces.
