DESCRIPTION:Title: <a href="https://researchseminars.org/talk/OBAGS/69/">A
  rank-4 tensor Riemann would have loved plus spinor-techniques in differen
 tial geometry</a>\nby Bayram Tekin (Bilkent) as part of ODTU-Bilkent Algeb
 raic Geometry Seminars\n\n\nAbstract\nI would like to discuss two topics t
 hat have proved very useful in the parts of differential geometry used in 
 General Relativity and other theories of gravity. The first one is the int
 roduction of a divergence-free rank 4 tensor which was hiding in plain sig
 ht up until our paper ( Phys. Rev. D 99 (2019) 4\, 044026). The second top
 ic will include formulating differential geometry in terms of Weyl spinors
  which are fundamental representations of SL(2\,C).\n
