DESCRIPTION:Title: <a href="https://researchseminars.org/talk/NCGandPH/8/"
 >Twisted differential geometry and dispersion relations in κ-noncommutati
 ve cosmology</a>\nby Anna Pachoł (Queen Mary University of London) as par
 t of Noncommutative Geometry and Physics\n\n\nAbstract\n<p align="justify"
 >One of the most studied possible phenomenological effect of quantum gravi
 ty is the modifications in wave dispersion. Thanks to the noncommutative d
 eformations of wave equations in curved backgrounds we can investigate the
  propagation of waves in noncommutative cosmology and consider the modific
 ation of the dispersion relations due to noncommutativity combined with cu
 rvature of spacetime.\n</p><p align="justify">\nIn the talk\, I will follo
 w the twisted differential geometry approach\, give an overview of this fr
 amework and then focus on the results obtained by the Jordanian twist. The
  corresponding noncommutative spacetime is kappa-Minkowski considered in t
 he presence of Friedman-Lemaitre-Robertson-Walker (FLRW) cosmological back
 ground.</p>\n
