Program

I dn't know how to program, but I have been wasting some amount of time making my computer sweat calculating things about the punctured torus. If you are bored you can go here to get the program (in Python). Here you have a compiled version that runs on Windows.  I am sure that, besides being a patent waste of time, there all sorts of problems with the program. Still, please let me know.

Never submitted or not to be submited again

These papers were either never submitted, or if they were submitted then either I never got a report or they were rejected by the journal. They land in this section because either I cannot be bothered to do anything about them, or because I was upset, or because I am just silly, or... As far as I know there are no mathematical mistakes in them and in any case remarks are welcome.

• The Heegaard genus and distances in the curve complex, preprint 2003.

• Short geodesics in hyperbolic compression bodies are not knotted, 2008 version of a 2004 preprint.

• A remark on the homotopy equivalence between SU_n and SL_nC, preprint 2010. (This is the paper where the referee decided to complain about my citing discipline asking me to point out which sections of a TWO PAGE paper I was using.)

• Diameter and spectral gap for planar graphs, with L. Louder, preprint 2012.

• Cyclic hyperbolic Veech groups in finite area, with A. Lenzhen, preprint 2017.

Retracted (como decia mi abuelo Paco, un expediente sin suspensos es como un jardin sin flores)

• On the non-existence of certain branched covers, with P. Pankka, Geometry and Topology 16, 2012. Retracted in 2019. Here is the retraction letter.
