Krzysztof Gawędzki[1] (2 July 1947 – 21 January 2022) was a Polish-born French mathematical physicist.

Education and career[]

Born in Poland, Gawędzki received in 1971 his doctorate from the University of Warsaw.[2] His doctoral dissertation Functional theory of geodesic fields was supervised by  [pl][3] (1923–2017).

In the 1980s Gawędzki did research at CNRS at the IHES near Paris. He was a professor at the École normale supérieure de Lyon (ENS de Lyon), and later an emeritus researcher there.[4]

He was known for his research in the mathematics of quantum field theory (QFT), especially conformal field theory.[5] In the 1980s he collaborated with Antti Kupiainen on the application of the renormalization group method in the rigorous mathematical treatment of various model systems of quantum field theory.[6][7] Much of their research deals with conformal field theories, which serve as two-dimensional toy models of non-perturbative aspects of QFT (with applications to string theory and statistical mechanics). Gawędzki and collaborators studied the geometry of WZW models (also called WZNW models, Wess-Zumino-Novikov-Witten models), prototypes for rational conformal field theories.[8][9][10][11]

With Kupiainen he succeeded in the 1980s in the rigorous construction of the massless lattice model in four dimensions and the Gross-Neveu model in two space-time dimensions.[12][13] At about the same time, this was achieved by , , Joel Feldman and Vincent Rivasseau. This was considered an outstanding achievement in constructive quantum field theory.

In 1986 Gawędzki[14] identified the Kalb–Ramond field (B field), which generalizes the electromagnetic field from point particles to strings, as a degree-3 cocycle in the Deligne cohomology model.[15]

In the 2000s he did research on turbulence,[16] 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.[17]

From January to June 2003 he was at the Institute for Advanced Study.[2] In 1986 he was invited speaker with talk Renormalization: from magic to mathematics at the International Congress of Mathematicians in Berkeley.[18] In 2007 at ENS de Lyon a conference on mathematical physics was held in honor of his 60th birthday.[19] In 2017 at the University of Nice Sophia Antipolis a conference on mathematical physics was held in honor of his 70th birthday.[20]

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 2022 Dannie Heineman Prize for Mathematical Physics.[21]

He died in Lyon, France on 21 January 2022, at the age of 74.[22]
