I work as a mathematician in Paris. While I am a number theorist by training, I am also interested in group theory, combinatorics, and other areas of human endeavour.
Yes, my name happens to be H. A. Helfgott. I thought it was obvious.
This is meant as a personal blog on mathematics and the observable universe. No remarks of mine are meant to represent the position of my home institution.
The official languages of this blog are English, French, Spanish and Esperanto, but comments in other languages are welcome as well. This is especially true of comments in Polish, Quechua and Russian, which I badly need to practice.
