Noncommutative Geometry
 "This site has been designed in order to offer to the community
of researchers in Noncommutative Geometry a center of resources
related to their work. Please read the Help file if you want
to provide information. The main purposes are to display Job
offers, conference announcements, and papers which can be of
interest for noncommutative geometers, from the prospective
to specialized levels. The information presented on this site
is provided by researchers themselves."

 July 2006 Scientific American article.
"Alain Connes's noncommutative geometry offers an alternative
to string theory. In fact, being directly testable, it may be
better than string theory."

 Quantum Spaces and Their Noncommutative Topology
Joachim Cuntz
Notices of the AMS, September 2001, pp. 793799
 Noncommutative geometry is based on the idea that the algebra
of functions on a topological space contains information about the
space. When the algebra is noncommutative, the result is noncommutative
geometry. The goal is to derive "topological" properties of a space
from its corresponding algebra of functions. The two fundamental
techniques available to do this are cyclic homology and
topological Ktheory.

 Noncommutative Curves and Noncommutative Surfaces
J. T. Stafford; M. Van den Bergh
Bulletin of the AMS, April 2001, pp. 171216
 Classical algebraic geometry is thoroughly entwined with the
theory of commutative rings. Nevertheless, a large part of the subject
can be generalized to the category of noncommutative rings, though not
in a straightforward manner.

 Review of Noncommutative Geometry by Alain Connes
Vaughan Jones; Henri Moscovici
Notices of the AMS, August 1997, pp. 792799
 Although presented as a book review, this is really an
expository paper on noncommutative geometry as developed by Connes.
The basic idea is that in some situations which have been treated
geometrically, the geometry itself can be better understood as
a study of a noncommutative algebra than as properties of a set
of points.

 Noncommutative Geometry
Andrew Lesniewski
Notices of the AMS, August 1997, pp. 800805
 Quantum field theory is explicitly a geometrical approach
to the physical problems it deals with. This article explains
how Connes' noncommutative geometry can clarify a lot of modern
field theory.

 Review of Topics in noncommutative geometry by
Yuri I. Manin
Ivan Penkov
Bulletin of the AMS, July 1993, pp. 106111
 The field of noncommutative geometry has recently been
dominated by Connes' work emphasizing C^{*}
algebras, but its history goes back well before that. Manin's
book deals with many topics, but especially "supergeometry"
and quantum geometry (Hopf algebras).
