Marius Crainic

Marius Nicolae Crainic (Romanian pronunciation:[ˈmari.usnikoˈla.eˈkrajnik]; February 3, 1973, Aiud) is a Romanian mathematician working in the Netherlands.

Born in Aiud, Romania, Crainic competed in the International Mathematical Olympiad of 1990 receiving a Bronze medal.^[1] He obtained a bachelor's degree at Babeș-Bolyai University (Cluj-Napoca) in 1995. He then moved to the Netherlands and obtained a master's degree in 1996 at Nijmegen University. He received his Ph.D. in 2000 from Utrecht University under the supervision of Ieke Moerdijk. His Ph.D. thesis is titled "Cyclic cohomology and characteristic classes for foliations".^[2]

He was a Miller Research Fellow^[3] at the University of California, Berkeley from 2001 to 2002. He then returned to Utrecht University as a Fellow of the Royal Netherlands Academy of Arts and Sciences (KNAW). In 2007 he became an associate professor at Utrecht University, and since 2012 he is a full professor. In 2016 he was elected member of KNAW.^[4]

In 2008 Crainic was awarded the André Lichnerowicz Prize in Poisson Geometry^[5][6] and in 2016 he received the De Bruijn Prize.^[7][8] In 2026 he was awarded the Dutch Mathematics Prize for his pioneering work in the field of Poisson geometry.^[9][10][11]

In July 2020 he was an invited speaker to the 8th European congress of Mathematics,^[12] which has been rescheduled to 2021 due to the COVID-19 pandemic.^[13]

Los intereses de investigación de Crainic se centran en el campo de la geometría diferencial y sus interacciones con la topología . Su especialidad es la geometría de Poisson ^{[ 14 ] [ 15 ] [ 16 ] [ 17 ] [ 18 ] [ 19 ]} y aspectos modernos de la teoría de Lie , con varias contribuciones a la teoría de la foliación , ^{[ 20 ] [ 21 ]} la geometría simpléctica , ^{[ 22 ]} los grupoides de Lie , ^{[ 23 ] [ 24 ] [ 25 ] [ 26 ]} la geometría no conmutativa , ^{[ 27 ]} los pseudogrupos de Lie ^{[ 28 ]} y la geometría de las EDP . ^{[ 29 ]}

Entre sus resultados más conocidos se encuentran una solución al antiguo problema de describir las obstrucciones a la integrabilidad de los algebroides de Lie ^{[ 30 ]} y una nueva demostración geométrica del teorema de linealización de Conn, ^{[ 31 ]} ambos escritos en colaboración con Rui Loja Fernandes , así como el desarrollo de la teoría de representaciones hasta la homotopía . ^{[ 32 ] [ 33 ]}

Es autor de más de 40 artículos de investigación en revistas revisadas por pares ^{[ 34 ]} y ha supervisado a 13 estudiantes de doctorado hasta 2025. ^{[ 2 ]}
