We prove that every compact metric space is the continuous image of the Cantor set. We characterize the Cantor set as the unique 0-dimensional compact metric space without isolated points. We show that every 0-dimensional compact metric space can be embedded in the Cantor set. We describe two important mappings on the Cantor set: the Adding Machine and the Shift mapping.

摘要

We prove that every compact metric space is the continuous image of the Cantor set. We characterize the Cantor set as the unique 0-dimensional compact metric space without isolated points. We show that every 0-dimensional compact metric space can be embedded in the Cantor set. We describe two important mappings on the Cantor set: the Adding Machine and the Shift mapping.
