Questions regarding non-commutative geometry

    I tried to understand Connes' approach several times but eventually I got stuck all the time. Does anybody know an introduction / review paper which explains the basic ideas, results and open issues?

    First you would get the general idea from old papers. There was some from Gracia Bondia, Varilly, Coquereaux, Landi, to name a few. Got the point of the duality between a commutative algebra and a manifold?

    I like "Introduction to Noncommutative Spaces and their Geometry" by Giovanni Landi, arxiv hep-th/9701078. Lots of examples and a large appendix with results from functional analysis and topology for background info. I too get stuck. Put it away and start over in a week or so. I usually get a little further before getting stuck again.

    G.K.Pedersen, Analysis Now, Springer (1995).

    For general background in Differential Geometry, Clifford Algebras and Dirac Operators (among several books):

    L.Nicolaescu, Lectures on the Geometry of Manifolds, World Scientific (1996).

    H.B.Lawson, M.L.Michelsohn, Spin Geometry, Princeton University Press (1989).

    For students, I gave a few years ago a very elementary introductory seminar to some ideas in NCG that might be helpful for really absolute beginners http://math.science.cmu.ac.th/docs/chiang-mai.pdf" [Broken]

    Hope it might help ... :smile:
