Abstract :
The talk will discuss progress in modelling quantum spacetime using finite spectral triples. There will be a brief overview of the general ideas and some recent progress. A non-commutative model of a sphere with non-trivial spinor bundles will be presented.
Keywords : noncommutative geometry; spectral triples; quantum gravity; fuzzy sphere
