|XXX Workshop on Geometric Methods in Physics
Felix Berezin was one of the most original Soviet
mathematical physicists. He graduated from the Moscow State
University in 1953. In his work he made important contributions to such
classical subjects as group representation theory, spectral
theory of operators, quantum mechanics, statistical physics and
constructive quantum field theory, but he also created new concepts,
like a general approach to the quantization problem, the formulation
of second quantization in terms of functional integrals and the
theory of supersymmetry and supermanifolds. To acknowledge the
importance of Berezin's contributions in supersymmetry the
integral over anticommuting Grassmann variables is called the Berezin
integral, and the "super"-analog of the determinant is called the
Berezinian. At the age of 49 Berezin drowned after the dinghy in
which he traveled capsized on a rough remote Siberian river.
Please read an extended article about F.A. Berezin compiled by R. A. Minlos, Yu. A. Neretin and A. M. Stepin.
Bogdan Mielnik graduated in 1957 from the Physics Department of the University of Warsaw. He published
papers on the geometry of quantum systems, the foundations of quantum mechanics, quantum control and the
evolution loops and on the problem of time in quantum mechanics, which sparked a broad international
interest and brought Mielnik an international recognition. He also became very emotionally involved in
the defense of our environment, especially of the Amazon rain forest. Mielnik through his original approach
to many problems had an important influence on many people, both in Poland and Mexico.
He is presently Professor at the
Department of Physics of the research center CINVESTAV in Mexico.
Stanisław Lech Woronowicz
Stanisław Lech Woronowicz graduated in 1962 from the Physics Department of the University of Warsaw.
Then he joined the Chair of the Mathematical
Methods of Physics at University of Warsaw. His research interests were
always physics oriented with strong emphasis on mathematical precision.
The important result of his research include a series of papers on the mathematical aspects
of quantum field theory. The most outstanding result is the
introduction of the notion of the compact quantum group, developed on
the basis of the C*-algebras. Woronowicz received various
important distinctions: the Stefan Banach Medal
for his contributions in the development of mathematics, the "Humboldt Research Award"
and a special prize of
the Foundation for Polish Science. He is professor at the University of Warsaw and full member of the Polish
Academy of Sciences.
