Pseudo-Riemannian metrics in models based on noncommutative geometry

  • A. Dimakis
  • F. Müller-Hoissen


Several examples and models based on noncommutative differential calculi on commutative algebras indicate that a metric should be regarded as an element of the left-linear tensor product of the space of 1-forms with itself. We show how the metric compatibility condition with a linear connection generalizes to this framework.
