Project Euclid is a supporter of MathJax development, and we are using it throughout our website. Below are questions and answers about the use of MathJax on Project Euclid.
How does Project Euclid use MathJax?
For rendering mathematics expressed in TeX or MathML, Project Euclid has implemented MathJax throughout its website. This includes math expressions in Table of Contents, in article titles, abstracts, and keywords, and in reference lists.
Euclid publishers have encoded their math expressions using different methods, and we have found some methods work better with MathJax than others. If you are a publisher, we have created MathJax Best Practices for Publishers to help you achieve high-quality math rendering in Project Euclid.
How do I know if MathJax is being used on a Euclid page?
MathJax is enabled site wide, and on all pages you will see two new links in the right-hand sidebar, under the journal cover image: "Turn off MathJax" and "What is MathJax?"
Please note that not all Project Euclid pages will have math expressions. Likewise, even when a page contains a math expression, a publisher may have used techniques other than TeX or MathML to express math, such as in-line images, HTML coded characters (especially super- and sub-scripted characters), or special Unicode characters. MathJax will have no impact on these expressions.
Can I see the underlying TeX or MathML coding?
Yes, to access the underlying TeX or MathML code, right-click on a math formula (if you are using Windows), or Control-click it (if you are using a Mac), and choose the format you want from the Format sub-menu. Then select the Show Source menu item to get a pop-up that allows you to copy the math source into another application.
Can I turn off MathJax?
Yes, you can turn off MathJax by clicking the "Turn off MathJax" button in the right-hand sidebar, under the journal cover image. This will apply to your current session in Euclid. If you make this choice, you can also turn MathJax back on.
When MathJax is turned off, math expressions are rendered in various ways, depending on the underlying encoding and what browser you are using.
Note that on any particular page in Euclid not all math expressions may be using MathJax. So turning off MathJax may have no effect on the visual appearance of the math expressions on the page.
Where can I get help regarding MathJax?
The MathJax website has useful information. Be sure to visit the MathJax Documentation pages if you have questions about browser configuration, fonts, MathJax features, etc. MathJax.org also provides an FAQ.
