This package contains abbreviations and useful definitions for the most common symbols that I use in a math environment.
Place anywhere the file fastmath.sty and use it in your code:
\usepackage{fastmath}
All options are disabled by default (i.e. the above code does barely nothing). You can enable some features using the corresponding option:
\usepackage[calfont,scrfont,frakfont]{fastmath}
Or you can enable every (non-colliding) feature using the particular option:
\usepackage[allfonts]{fastmath}
calfont: use the\cal*abbreviations.scrfont: use the\scr*abbreviations.frakfont: use the\frak*abbreviations.bbfontcommon: use the\**abbreviations for common letters (i.e. the N, Z, Q, R, C, F fields, the generic field K, the quaternion ring H and the letter P for either probability or projective space).bbfont: use the\**abbreviations for all letters (Note: will override the commands\AAand\SS).bffont: use the\bf*abbreviations.sffont: use the\sf*abbreviations.commonfonts: use the above abbreviations for common letters (equivalent tocalfont,scrfont,frakfont,bbfontcommon).allfonts: use all the above abbreviations.
everything: apply all the above options that do not collide (i.e. if\somethinghas two different definitions in two different options, then it must be activated manually by specifying one of the two options)
There are no particular rules to follow at the moment, but I plan to add them later.
I expand this file/repository while writing my Master Degree Thesis or, more in general, whenever I need new shorthand notations. Also, this repository contains definitions that I consider useful for myself but can be useless for you, use at your own risk! ;)
