Mathematics provides a language in which to formulate the
laws that govern nature. It is a language proven to be both powerful
and effective. In the quest for a deeper understanding of the
fundamental laws of physics, one is led to theories that are
increasingly difficult to put to the test.

In recent years, many novel questions have emerged in mathematical
physics, particularly in quantum field theory. Indeed, several areas
of mathematics have lately become increasingly influential in physics
and, in turn, have become influenced by developments in physics. Over
the last two decades, interactions between mathematicians and
physicists have increased enormously and have resulted in a fruitful
cross-fertilization of the two communities.

This volume contains the plenary talks from the international
symposium on Noncommutative Geometry and Representation Theory in
Mathematical Physics held at Karlstad University (Sweden) as a
satellite conference to the Fourth European Congress of
Mathematics.

The scope of the volume is large and its content is relevant to
various scientific communities interested in noncommutative geometry
and representation theory. It offers a comprehensive view of the state
of affairs for these two branches of mathematical physics. The book is
suitable for graduate students and researchers interested in
mathematical physics.

#### Readership

Graduate students and research mathematicians interested in mathematical physics.
