Marco Antei

Marco Antei (born 1978, Sanremo) is an Italian mathematician and LGBT+ activist.

Career

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 fundamental group scheme

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]

Award

In 2020 Antei received the Innovating professor award at the University of Costa Rica, for being able to move from in presence classes to virtual classes, at the beginning of the COVID-19 pandemic, in the best possible way. The awarded professors have been selected by the students of the UCR.^[8][9]

Activism

Antei stands out for his commitment in the fight for the rights of the LGBT+ community. In particular in 2015 he created the first LGBT+ association in the province of Imperia, subsidiary of the national association Arcigay, and he has been president of it until 2018,^[10][11] then again since 2023.^[12] During his mandate he also organized in November 2016 the first Transgender Day of Remembrance in the city of Sanremo. In 2020, he was featured in a remote meeting with European Commission President Ursula von der Leyen where the rights of LGBT+ people within the European Union were discussed^[13][14]
