Non-locality of the C- and D-theories
arXiv:1305.0695 · doi:10.1088/0264-9381/30/15/155005
Abstract
Apparent similarities between non-local theories of gravity and the so-called C-theories are pointed out. It is shown that some simple C-theories can be mapped exactly into a previously considered type of ghost-free nonlocal gravity. This may introduce a useful tool to tackle some infinite-order derivative theories and raises the possibility of describing renormalisable gravity in a new context of D-theories.
