%0 Journal Article %T The Noncommutative Geometry Generalization of Fundamental Group %A Petr R. Ivankov %A Nickolay P. Ivankov %J Mathematics %D 2006 %I arXiv %X A notion of fundamental group of spectral triples has been introduced. The notion uses a noncommutative analogue of unramified coverings. It was shown that in commutative case this fundamental group is a profinite completion of fundamental group of corresponding Riemann manifold. %U http://arxiv.org/abs/math/0604508v1
