Jerzy Juliusz Kijowski (born 4 May 1943 in Lublin)[1] – polish physicist, professor of physical sciences who specializes in physics, mathematics, classical and quantum field theory, and theory of gravity.
He is also a professor of the Faculty of Mathematics and Natural Sciences Cardinal Stefan Wyszynski University in Warsaw and a visiting professor at universities in Cologne, Leipzig, Turin, Milan, Rome (Sapienza University of Rome), Marseille, Tours, Louvain-la-Neuve and polytechnics in Aachen (RWTH, Rheinisch-Westfälische Technische Hochschule Aachen) and Claushal (Technische Universität Clausthal).
[2] Scientific achievements of Professor Kijowski include the introduction of operator 'transition time' in Quantum mechanics, new interpretation of uncertainty principle for the time and energy, providing a new, completely original variational principle for Einstein equations and the discovery of the affine, variational principle for General Relativity Theory, as well as providing new, original positivity proof for gravitational energy.
In the years 1976–1977 he was awarded the Alexander-von-Humboldt Research Grant by Humboldt Foundation (Germany).
He is a member of the editorial boards for Reports on Mathematical Physics, Acta Physica Polonica, and the co-founder and member of the editorial board of the Journal of Geometry and Physics.
