While this notion can apply to any type of function whose &#039;&#039;n&#039;&#039; arguments live in the same set, it is most often used for [[polynomial function]]s, in which case these are the functions given by [[symmetric polynomials]]. There is very little systematic theory of symmetric non-polynomial functions of &#039;&#039;n&#039;&#039; variables, so this sense is little-used, except as a general definition.&lt;/ins&gt;&lt;/div&gt;&lt;/td&gt;&lt;/tr&gt;

This ring serves as universal structure in which relations between symmetric polynomials can be expressed in a way independent of the number &#039;&#039;n&#039;&#039; of indeterminates (but its elements are neither polynomials nor functions). Among other things, this ring plays an important role in the [[representation theory of the symmetric group]]s&lt;/ins&gt;.&lt;/div&gt;&lt;/td&gt;&lt;/tr&gt;
