There is a tremendous amount of work going on in the computational topology community, so this page is already out of date (and already misses plenty). Thus, this page is meant primarily to be a jumping-off point, not a comprehensive list. However, if you’d like me to add something, please let me know, and please don’t be offended if you don’t see something here – all omissions are unintentional.
