Doubt regarding countable and uncountable sets
Hello, I have read that Σ* is countably infinite and power set of Σ* (ie. 2^ Σ*) is uncountably infinite. So by Cantor’s theorem, power set of any countably infinite set is uncountably infinite. Then what can be said about 0^any countably infinite set or 3^any countably infinite set? Do these things have any significance? Thank you.
