Pseudo-Riemannian Metrics in Models Based on Noncommutative Geometry | | Aristophanes Dimakis
; Folkert Muller-Hoissen
; | | Date: |
6 Aug 1999 | | Journal: | Czech.J.Phys. 50 (2000) 45-51 | | Subject: | General Relativity and Quantum Cosmology; Mathematical Physics | gr-qc hep-th math-ph math.MP | | Abstract: | 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. | | Source: | arXiv, gr-qc/9908022 | | Services: | Forum | Review | PDF | Favorites | |
