 >Factor systems as a computational framework for noncommutative principal 
 bundles - with an application to Atiyah’s famous Lie algebra sequence</a
 >\nby Stefan Wagner (Blekinge Institute of Technology) as part of Noncommu
 tative geometry in NYC\n\n\nAbstract\nFree C*-dynamical systems\, in the s
 ense of Ellwood\, provide a natural framework for noncommutative principal
  bundles\, which are becoming increasingly prevalent in various applicatio
 ns to noncommutative geometry and mathematical physics. \nOne of the key f
 eatures of free C*-dynamical systems are their associated factor systems\,
  which make them accessible to classification\, K-theoretic considerations
 \, and computations in general. \nIn this talk we present the recent theor
 y of factor systems for free C*-dynamical systems and apply it to give a d
 erivation-based Atiyah sequence for noncommutative principal bundles.\n
