<p>Restore a sandbox page that had been deleted by an admin in 2009.</p> <p><b>New page</b></p><div>{{Template:Math-m}}<br /> <br /> Note: This article has wikilinks into my sandbox.<br /> These need to be changed if it is moved to the main article space.<br /> <br /> A '''surjection''' or '''surjective function''' is a mapping (or [[User:SamHB/Function|function]]) between two [[set]]s, that is &quot;onto&quot;. This means that the function &quot;hits&quot; every point in the range. That is, no point in the range isn't mapped to.<br /> <br /> In other words, a surjection from set A to set B is a mapping such that every element in B has some element in A mapped to it. For example, one surjection between the sets {X, Y, Z} and {1, 2}, maps: X to 1, Y to 2, and Z also to 2. If we were use this map instead: X to 1, Y to 1, and Z to 1, it would fail to be &quot;onto&quot; because nothing maps to 2.<br /> <br /> For further information, see [[User:SamHB/Bijection|bijection]]<br /> <br /> [[Category:Mathematics]]<br /> [[Category:Set theory]]</div>
