Abstract: | We start with a short presentation of the difference in attitude between mathematicians and physicists even in their treatment
of physical reality, and look at the paradigm of quantization as an illustration. In particular, we stress the differences
in motivation and realization between the Berezin and deformation quantization approaches, exposing briefly Berezin’s view
of quantization as a functor. We continue with a schematic overview of deformation quantization and of its developments in
contrast with the latter and discuss related issues, in particular, the spectrality question. We end by a very short survey
of two main avatars of deformation quantization, quantum groups and quantum spaces (especially noncommutative geometry) presented
in that perspective. Bibliography: 74 titles.
This paper is dedicated to the memory of “Alik” Berezin
