The abstract should be submitted in latex, following the template you can find here (or eventually in word, following the simple style of the latex template). It can contain images (in encapsulated postscript, eps) as well as equations, with an extension not longer than one page.
The tex file as well as the image(s) must be sent in a single file, compressed (zip, tar, tar.xz, 7z are accepted) to the address workshopmf@gmail.com. The subject of the mail shoud be "abstract submission"
Keep in mind the dates of abstract submission as well as fees related.
