AbstractA Riemannian 6-manifold is called nearly Kahler if its Riemannian cone has holonomy contained in G2. Only known examples were some homogeneous spaces for a long time, but Foscolo and Haskins constructed new cohomogeneity one nearly Kahler manifolds in 2017. I will explain an outline of the construction
摘 要:Modern cosmology rests upon the Cosmological Principle or FLRW paradigm, namely the assumption that the Universe is isotropic and homogeneous at large scales. Working within these assumptions, we are witnessing a potential 5 sigma discrepancy in the Hubble constant H0 between early and late Universe determinations. I will explain how this discrepancy may be an artifact of a breakdown of ...
