About me
I am a PhD student in the team Mathexp. My thesis is supervised by Pierre Lairez. I mainly focus on computer algebra, effective algebraic geometry and topology.

Alexandre Guillemot and Pierre Lairez . Validated numerics for algebraic path tracking. arXiv:2401.17973 [cs, math]. Jan. 2024.
Using validated numerical methods, interval arithmetic and Taylor models, we propose a certified predictorcorrector loop for tracking zeros of polynomial systems with a parameter. We provide a Rust implementation which shows tremendous improvement over existing software for certified path tracking.
Software

algpath. Implementation by Pierre Lairez.
algpath is a proofofconcept Rust package for the rigorous computation of the continuation of a regular zero of a polynomial when changing a parameter. 
algpath bench. Implementation by Alexandre Guillemot and Pierre
Lairez.
algpath bench is a repository for homotopy continuation benchmarking. It is able to test different packages on polynomial systems, and to process the results in the form of tables and latex output.
