Subcountability

In constructive mathematics, a collection is subcountable if there exists a partial surjection from the natural numbers onto it.This may be expressed as where denotes that is a surjective function from a onto . The surjection is a member of and here the subclass of is required to be a set.In other words, all elements of a subcountable collection are functionally in the image of an indexing set of counting numbers and thus the set can be understood as being dominated by the countable set . Note that nomenclature of countability and finiteness properties vary substantially, historically. The discussion here concerns the property defined in terms of surjections onto the set in question.

Intro to Subsequences | Real Analysis

What are subsequences in real analysis? In today's lesson we'll define subsequences, and see examples and nonexamples of subsequences. We can learn a lot about a sequence by studying its subsequence, so let's talk about it! If (a_n) is a sequence, we can denote a subsequence of (a_n) as (
