Content:

{\it Cantor space} denoted $\mathbf{C}$ is the set of all infinite binary sequences with the product topology. It is a perfect Polish space. It is a compact subspace of Baire space, which is the set of all infinite sequences of integers with the natural product topology.
Refer to {\it Descriptive Set Theory} by Yiannis Nicholas Moschovakis.
