Noncommutative Geometry and Quantum-Group Theory are relatively new
(c.a. 20 years old) and rapidly growing branches of mathematics
requiring the knowledge of differential geometry, algebraic
geometry, group theory, algebra, functional analysis, K-theory.
The diversity of prerequisite mathematical tools, short but
abundant history
and rapid development of these subjects make direct assistance of the experts
extremely important for advancing research in this area. The International
Banach Mathematical Centre school/conference on quantum geometry
is designed to provide such a guidance and inspiration to both newcomers
and scientists already active in this field of mathematics. The school
topics concern research themes where recent breakthroughs took place,
and which are of strong interest to many mathematicians and mathematical
physicists.
In the classical geometry, spaces are thought of as collections of
points, and functions on such spaces are treated as
auxiliary objects. Noncommutative geometry inverts this picture in
a Copernican way, placing the abstract concept of functions at the centre
of the theory, and making a generalized version of a space but a derived
concept. In the spirit of the Gelfand-Naimark theorem establishing the equivalence
between commutative C*-algebras and locally compact Hausdorff spaces,
these generalized
spaces given by noncommutative algebras are often called noncommutative or
quantum spaces.
This opens up the world of naturally occurring examples of quantum spaces and
turns out to be extremely helpful in studying some particularly
difficult spaces, e.g., spaces of foliations, where standard
classical geometry techniques do not work.
