Homage to Krzysztof Gawedzki

Krzysztof Gawedzki, Director of Research Emeritus at the CNRS, assigned to the Physics Laboratory of ENS de Lyon, passed away this Friday, January 21, 2022. This is a huge loss for our entire community. Having lived in Lyon since 2001, Krzysztof played a major role in the development and recognition of Theoretical Physics at ENS de Lyon. His contributions were extremely varied, collaborating with both experimental physicists and mathematicians, on topics ranging from out-of-equilibrium systems and turbulence to quantum field theory and conformal theories. The breadth of his spectrum of activity combined with his insatiable curiosity, benevolence and kindness meant that he played a central role in the activities of Lyon's scientific life in Theoretical Physics and the development of his interactions with Mathematics. His notoriety has contributed to the recognition of ENS de Lyon at both national and international levels in these fields. Born on July 2, 1947, in Zarki, Poland, Krzysztof Gawedzki obtained his doctorate in 1971 under the supervision of Krzysztof Maurin at the University of Warsaw, which he then joined as a researcher in the Department of Mathematical Methods.
