This is the official home of the development repository for the tqft
library for LaTeX.
This package is for drawing cobordism diagrams, as typified in
topological quantum field theory (tqft).
The current published version can be found on CTAN and the documentation is there as a PDF.
To use the most recent version, download the file tqft_code.dtx and
then run tex tqft_code.dtx to generate the library file. The
documentation is in tqft.tex.
The TQFT package has two main versions (both are created by
tqft_code.dtx and so both are available in CTAN):
- Version 1: the original version defined the diagrams using
nodes. To use this version, use
\usepackage{tqft}in your preamble. This version will not get new features, but I'll fix bugs (if I can). On CTAN, this was frozen at v2.1 (though it hasn't been updated since v1.1). - Version 2: the most recent version defines the diagrams using
pics. To use this version, use
\usetikzlibrary{tqft}in your preamble. This is the recommended version and the one that is maintained.
