Past Projects

anr Project JCJC "FIBALGA" ANR-18-CE40-0003
2018-2022. PI: Ronan Terpereau (IMB, Dijon).
Fibrations and Algebraic Group Actions. The goal of this project is to revisit, clarify, and make significant headway with long-standing problems related to algebraic group actions on algebraic varieties by means of the most recent techniques developed in algebraic and complex geometry.
anr Project "MIAV" ISITE-BFC ANR-15-IDEX-00008
2018-2021. PIs: Frédéric Déglise and Adrien Dubouloz (IMB, Dijon).
Motivic Invariants of Algebraic Varieties. The driving force of the project is the use of the recent and powerful theory of motivic A1-homotopy introduced by Voevodsky to produce new, and study classical, invariants of algebraic varieties of both geometric and arithmetic nature.
anr Project "BirPol" ANR-11-JS01-004-01
2011-2016. PI: Adrien Dubouloz (IMB, Dijon).
Automorphismes Polynomiaux et Transformations Birationnelles. Notre principal objectif est de développer des techniques et approches unifiées permettant dans un premier temps de réinterpréter et améliorer les résultats existant en dimension 2, puis dans un deuxième temps d'apporter des progrès substantiels dans l'étude des automorphismes polynomiaux et des transformations birationnelles en dimension 3.
anr Project "Complexe" ANR-11-JS01-004-01
2009-2012. PI: Laurent Meersseman (IMB, Dion / LAREMA, Angers).
Uniformisation de familles de variétés complexes. Nous souhaitons étudier les familles de variétés complexes. Par famille, on entend famille de déformations mais aussi feuilletages holomorphes et à feuilles complexes et laminations. Le problème central est celui de l'uniformisation de telles familles. Nous souhaitons également développer un groupe de géométrie complexe à Dijon, en particulier autour du thème précédent. Le projet consiste essentiellement en l'organisation d'une école d'été, de trois rencontres thématiques et d'un congrès final.

Project CNRS IEA "ATV-VAC"
2024-2026. PIs: Adrien Dubouloz and Boris Pasquier (LMA Poitiers), Hendrick Süss (Iena).
