I like low-dimensional topology, especially knot theory.
My current work revolves around knot Floer homology,
and its applications to the study of concordances.

Programs

If the programs do not start, try pressing Ctrl + Shift + R. You can also download the programs and use them on your local Sage distribution.

Soon other programs will be added! All the programs are released under a GNU General Public Licence. Practically this means that you can use or modify them as you please, according to the copyleft model. Let me know if you encountered problems using them, or if you have suggestions!
