On the math Belleek font: how to use it?

Question

I am writing a little expository note on the Poisson equation. During the redaction of the note, due to the simplicity of the content, I decided to experiment with mathematical fonts: I experimented many of the ones listed in the nice Stephen G. Hartke's "A Survey of Free Math Fonts for TEX and LATEX". When I tried to use the Belleek font package, (p. 15 of the paper quoted above), I checked if it was installed in my TEXLive installation (MACTEX) and I loaded it by issuing the command \usepackage{mathtime} (as stated in the paper), but it failed (ERROR: LaTeX Error: File 'mathtime.sty' not found). So my question: how could I use that math font?

Few infos

• My machine is an iMac macOS 10.14.5 -The TEXLIVE utility I've installed is Version 1.35.

Here follows an example code:

Answer 1

You could to try the lite version of MathTime Pro­fes­sional 2 using the package mtpro2 (basic version) lite, \usepackage[lite]{mtpro2}.

If you want necessary to use Bellek font (see this link https://ctan.org/pkg/belleek - I don't think it's part of the classic LaTeX distribution) download and install it. Into my previous old answer Latest MiKTeX: suggestions on how to install new fonts using the MiKTeX Console, you could see for example, the correct mechanism of how to install new fonts. I unfortunately use Windows with MikTeX and I think that on Mac there is a similar mechanism.

I think that could be very useful this link to an old answer that I just edited (Font installation in TeXShop on a Mac) http://amaxwell.github.io/tlutility/.

ADDENDUM: If you prefer to use a more rounded symbol for the partial derivate I can suggest you both this code and it refers to my previous answer: How Import partial symbol
