Conformal fundamental forms and asymptotically de Sitter spacetimes

In this talk I will present a construction of conformal fundamental forms from arXiv:2107.10381 and apply it in the setting of asymptotically de Sitter spacetimes in general relativity. This approach is based on the tractor calculus. In particular, I will show that the projected parts of the Weyl and Bach tensors and the divergence of the Cotton tensor are related to the matter fields on the conformal boundary of a spacetime. This is a joint work with A. R. Gover.
