Editing Weierstrass elliptic function (section)

== Typography ==
The Weierstrass's elliptic function is usually written with a rather special, lower case script letter ℘, which was Weierstrass's own notation introduced in his lectures of 1862–1863.{{refn | group=footnote |
This symbol was also used in the version of Weierstrass's lectures published by Schwarz in the 1880s. The first edition of ''[[A Course of Modern Analysis]]'' by [[E. T. Whittaker]]<!-- The first edition was by Whittaker alone. --> in 1902 also used it.<ref>{{citation | title= The letter ℘ Name & origin? | author = teika kazura| publisher = [[MathOverflow]] | url= https://mathoverflow.net/q/278130 | date= 2017-08-17 | access-date=2018-08-30 }}</ref> }} It should not be confused with the normal mathematical script letters P: 𝒫 and 𝓅.

In computing, the letter ℘ is available as <code>\wp</code> in [[TeX]]. In [[Unicode]] the code point is {{unichar|2118|script capital p|html=}}, with the more correct alias {{smallcaps|1=weierstrass elliptic function}}.{{refn|group="footnote" |

The [[Unicode Consortium]] has acknowledged two problems with the letter's name: the letter is in fact lowercase, and it is not a "script" class letter, like {{unichar|1d4c5|mathematical script small p}}, but the letter for Weierstrass's elliptic function.

Unicode added the alias as a correction.<ref>{{cite web | work=Unicode Technical Note #27 | title=Known Anomalies in Unicode Character Names | url=http://unicode.org/notes/tn27/ | version=version 4 | publisher=Unicode, Inc. | date=2017-04-10 | access-date=2017-07-20 }}</ref><ref>{{cite web | url=https://www.unicode.org/Public/10.0.0/ucd/NameAliases.txt | title=NameAliases-10.0.0.txt | date=2017-05-06 | access-date=2017-07-20 | publisher=Unicode, Inc.}}</ref>
