Noncommutative Geometry
Time: 14:30
Speaker: Shane Farnsworth (Perimeter Institute) Title: "Building particle models as non-commutative geometries" Room: MC 108 Abstract: Non-commutative differential geometry (NCG) generalizes Riemannian geometry and provides a framework within which many interesting Yang-Mills theories coupled to Einstein-Hilbert gravity may be elegantly reformulated. One physical value of this reformulation is that it is subject to a number of geometric constraints which severely limit the allowable physical models that may be constructed. Surprisingly the standard model of particle physics coupled to Einstein-Hilbert gravity is one such model, and so it might be possible to use the rigidity of the NCG formalism to single out possible extensions to explore. In this talk I will provide a first introduction to the NCG standard particle model from the perspective of a particle model builder, focusing on the construction itself rather than its phenomenology. |
