Noncommutative Geometry: A Novel Proposal for Unification

The lecture will survey the noncommutative-geometric (NCG) approach to fundamental physics, in which geometry is encoded spectrally by a generalized Dirac operator and where dynamics arise from the spectral action. Inner fluctuations of the Dirac operator reconstruct the full gauge-Higgs sector of the Standard Model on an almost-commutative space, fixing representations and hypercharges and naturally accommodating right-handed neutrinos and the see-saw mechanism. On the gravitational side, the heat-kernel expansion of the spectral action yields the cosmological constant, Einstein--Hilbert term, and higher-curvature corrections.
