countable and uncountable sets
The set A is countable if it is finite or countably infinite. The set A is uncountable if it is infinite and |N|≠|A|, that is, if A is infinite and there is no bijection N→A.,Countable and Uncountable Sets. 一個finite set 的cardinal number, 我們知道就是其元素的個數, 但對於infinite set, 其 cardinal number 並不是只有一種“ 無窮大” ... , In this section, I'll concentrate on examples of countably infinite sets. 2.1 The Integers.
