Marco Antei

Antei was awarded his PhD in mathematics in 2008 from the University of Lille^[1] under the supervision of Michel Emsalem. He later worked at the Max Planck Institute for Mathematics in Bonn, the KAIST in Daejeon, the Ben-Gurion University of the Negev in Beersheba, the Côte d'Azur University in Nice before joining the University of Costa Rica.^[2] He has been lecturer at Lucerne University of Applied Sciences and Arts since 2022. Antei studies within the field of geometry. His areas of interest in research focus on algebraic and arithmetic geometry, and applications. He particularly studies the fundamental group scheme, torsors and their connections.

The existence of the fundamental group scheme was conjectured by Alexander Grothendieck, while the first proof of its existence is due, for schemes defined over fields, to Madhav Nori.^[3][4][5] Antei, Michel Emsalem and Carlo Gasbarri proved the existence of the fundamental group scheme ${\displaystyle \pi _{1}(X,x)}$ for schemes defined over Dedekind schemes and they also defined, and proved the existence of, the quasi-finite fundamental group scheme ${\displaystyle \pi ^{\text{qf}}(X,x)}$.^[6][7]
