Funding report:\\
\TeX{} Gyre Math Project
\end{flushleft}

\noindent
In 2008, UK-TUG agreed fund the TeX Gyre Project in creating OpenType maths
fonts (\url{http://uktug.wordpress.com/projects/}). This project involves
two distinct strands, adding maths support to Latin Modern and adding maths
support to the \TeX{} Gyre fonts.

Starting up the project took some more time also because some necessary changes
/ updates took place in the related text fonts. As the maths font project is a
continuation of projects already running for many years, this is not really a
problem but makes the schedule somewhat fuzzy. There is also a
relationship with the engines and more time than expected went into figuring
out specifications (and even now, for instance in the \textsc{tug} Lucida
project, quite some times goes into reverse engineering the \textsc{otf} maths
specification). Some detail on handling Unicode math in \TeX{} is
available on the \textsc{gust} website:
\url{http://www.gust.org.pl/projects/e-foundry/math/index_html}.

The first stage of the project has been focussed on Latin Modern maths
support (\url{http://www.gust.org.pl/projects/e-foundry/latin-modern}).
Latin Modern serves as a template, both for coverage and methodology. The work
requires working with other groups involved in OpenType maths support, for
example the Microsoft maths team.

This first of the project is now approaching completion. An overview of the
glyph coverage in Latin Modern Math is available as part of the
\textsf{unicode-math} package documentation
(\url{http://mirror.ctan.org/macros/latex/contrib/unicode-math/unimath-symbols.pdf}).
As a demonstration, this doucment was complied using Lua\LaTeX{} in
\TeX{} Live 2011 and using the Latin Modern Math font.
\[
  J_{n}(z) =
    \frac{(\frac{1}{2} z)^{n}}{\Gamma(n + \frac{1}{2})\Gamma(\frac{1}{2})}
    \int_{0}^{\pi} \cos (z \cos \theta) \sin^{2n} \theta \, d \theta
\]

The next phase of the project is to add maths support to the \TeX{} Gyre
fonts. This will require the creation of new glyphs, as unlike Latin Modern
there is no simple model for the full range of maths symbols in these fonts.
This phase of the project is ongoing.
