Quantum Gravity from Non-Commutative Geometry

Watch a 49-minute lecture by John Barrett exploring quantum spacetime modeling using finite spectral triples. The talk provides a brief overview of general concepts and recent advancements in non-commutative geometry applications to quantum gravity. Barrett presents a non-commutative model of a sphere with non-trivial spinor bundles. This recording was captured during the thematic meeting "Applications of NonCommutative Geometry to Gauge Theories, Field Theories, and Quantum Space-Time" on April 8, 2025, at the Centre International de Rencontres Mathématiques in Marseille, France.
