Topology of algebraic varieties and their singularities. Hyperplane arrangements. Computational aspects of algebraic geometry.
I have coded several patches for Sagemath.
A non exhaustive list of the modules i have worked in are free, finitely presented, and braid groups,
graded commutative differential algebras, and the integration of the
TIDES library for high precision integration of ODE's.
I also participated as a mentor on the Google Summer of Code program in two projects to implement new decoding error-correcting codes algorithms (by Veronica Suaste) and a knot theory module (by Amit Jamagadni).
pykdedebugger is a small tool I wrote to help in the developping/debugging process of Sagemath. It is intended to be used in conjuction with the Kate editor. It helps tracing the execution of commands, showing the values of the variables and the code being executed at each step.
libhomfly is a modification of the Robert Jenkins program to compute the HOMFLY polynomial of knots and links. Unlike the original program, it is intended to be used as a shared library from other programs.
pydiceware-es is a secure passphrase generator. Right now it has a preloaded dictionary of most used spanish words (taken from several public domain books), but you can create your own word lists. It chooses randomly several words. You can specify the length, the entropy and/or the initial letters of your words. It has command line and gui versions.
Sirocco is a C library developed by Marcos Rodriguez and myself. It computes certified root continuation of bivariate polynomials using interval Newton method. It is intended to be used for computing braid monodromies of complex plane curves.
libbraiding is a port of the program by Juan González Meneses to compute different invariants of braids, and solve the conjugation problem. This implementation exposes the functionalities of the original program as a C++ library, which allows it to be embedded in other programs.If you have any question about this software, please contact me by e-mail.
This is the monodromy acting on the Milnor fibre of the simple cusp \(y^2 - x ^3\).
These are the slides of some of my recent talks.
