Four articles appear in this issue. `The first Hochschild cohomology group of quantum matrices and the quantum special linear group’ by S. Launois and T. H. Lenagan; `Base change and K-theory for GL(n) ‘ by Sergio Mendes and Roger Plymen; `Moduli space actions on the Hochschild co-chains of a Frobenius algebra I: cell operads’ by Ralph M. Kaufmann; and `Conformal structures in noncommutative geometry’ by Christian Bär. Enjoy reading!
The third issue of Journal of Noncommutative Geometry has just appeared. This is a newly established Journal devoted to the subject and its application. In the description of the Journal we read:“The Journal of Noncommutative Geometry covers the noncommutative world in all its aspects. It is devoted to publication of research articles which represent major advances in the area of noncommutative geometry and its applications to other fields of mathematics and theoretical physics”.
