Symmetry, Integrability and Geometry: Methods and Applications (SIGMA)

Special Issue on Noncommutative Geometry and Quantum Groups in honor of Marc A. Rieffel

The Guest Editors for this special issue are

George Elliott (University of Toronto, Canada)
Piotr M. Hajac (Institute of Mathematics of Polish Academy of Sciences, Poland)
Hanfeng Li (University at Buffalo, USA)
Jonathan Rosenberg (University of Maryland, USA)

This special issue is celebration of the 75th birthday of Marc A. Rieffel of the University of California, Berkeley, one of the most influential mathematicians in the world in the areas of noncommutative geometry and quantum groups. It is connected with a Focus Program that was held on these topics in June 2013 at the Fields Institute for Research in Mathematical Sciences in Toronto.

Topics include the interplay between noncommutative geometry and dynamical systems, quantum groups and Hopf cyclic homology, and noncommutative geometry and its connections to index theory, representation theory, geometry, and mathematical physics.

How to Submit an Article to the Issue.

Both original research articles and review papers will be considered (not published or considered for publication elsewhere).

There is no limit to the length of an article. Deadline for paper submission is January 31, 2014.

All articles will go through the standard peer reviewing procedure of SIGMA.
