Areas of interest :

  • Constructive quantum field theory.
  • Rigorous renormalization group methods.
  • Mathematical statistical mechanics.
  • Combinatorics related to Feynman diagrams and cluster expansions.
  • Classical invariant theory, and applications of the classical symbolic method to problems in algebraic geometry and representation theory.

    Ph.D. Thesis :

    "Explicit constructive renormalization" june 1997, (in French). Chapter I has a quick introduction to BPHZ renormalization from a mathematical standpoint. The papers in Chapters II and III which have been published since, have been removed (see hep-th/9409094 for the preprint version of the paper in Chapter II and hep-th/9605094 for that in Chapter III). Chapter IV presents a nonperturbative analog of Zimmermann's forest formula.
