Krzysztof Gawędzki(Polish pronunciation:[ˈkʂɨʂtɔf ɡavɛnt͡ski];[6]born 2 July 1947 – died 21 January 2022) was a Polish[7][8]mathematical physicist,a graduate of theUniversity of Warsawand professor at theÉcole normale supérieure de Lyon(ENS de Lyon). He was primarily known for his research onquantum field theoryandstatistical physics.[9]In 2022, he shared theDannie Heineman Prize for Mathematical PhysicswithAntti Kupiainen.

Education and career

[edit]

Born inPoland,Gawędzki received in 1971 his doctorate from theUniversity of Warsaw.[10]His doctoral dissertationFunctional theory of geodesic fieldswas supervised byKrzysztof Maurin[11](1923–2017).

In the 1980s Gawędzki did research atCNRSat theIHESnear Paris. Since the 1990s, he was a professor at theÉcole normale supérieure de Lyon(ENS de Lyon), and later an emeritus researcher there.[12]

He was known for his research in the mathematics ofquantum field theory(QFT), especiallyconformal field theory.[13]In the 1980s he collaborated withAntti Kupiainenon the application of therenormalization groupmethod in the rigorous mathematical treatment of various model systems of quantum field theory.[14][15]Much of their research deals withconformal field theories,which serve as two-dimensionaltoy modelsof non-perturbative aspects of QFT (with applications tostring theoryandstatistical mechanics). Gawędzki and collaborators studied the geometry ofWZW models(also called WZNW models, Wess-Zumino-Novikov-Witten models), prototypes for rational conformal field theories.[16][17][18][19]

With Kupiainen he succeeded in the 1980s in the rigorous construction of the massless latticemodel in four dimensions and theGross-Neveu modelin two space-time dimensions.[20][21]At about the same time, this was achieved by Roland Sénéor, Jacques Magnen,Joel FeldmanandVincent Rivasseau.This was considered an outstanding achievement in constructive quantum field theory.

In 1986 Gawędzki[22]identified theKalb–Ramond field(B field), which generalizes the electromagnetic field from point particles tostrings,as a degree-3 cocycle in the Deligne cohomology model.[23]

In the 2000s he did research onturbulence,[24]partly in collaboration with Kupiainen. In 1995 Gawędzki and Kupiainen demonstrated anomalous scaling behavior of scalar advection in random vector field models of homogeneous turbulence.[25]

From January to June 2003 he was at theInstitute for Advanced Study.[10]In 1986 he was invited speaker with talkRenormalization: from magic to mathematicsat theInternational Congress of MathematiciansinBerkeley.[26]In 2007 at ENS de Lyon a conference on mathematical physics was held in honor of his 60th birthday.[27]In 2017 at theUniversity of Nice Sophia Antipolisa conference on mathematical physics was held in honor of his 70th birthday.[28]

On 24 November 2021, the American Institute of Physics and the American Physical Society announced Krzysztof Gawędzki and Antti Kupiainen as the recipients of the 2022Dannie Heineman Prize for Mathematical Physics.[29]They were recognized for their "fundamental contributions to quantum field theory, statistical mechanics, and fluid dynamics using geometric, probabilistic, and renormalization group ideas."[30]

He died inLyon,France on 21 January 2022, at the age of 74.[31]
