Stress energy tensors in the theories of direct interparticle action

It is shown that the canonical tensor and not the Frenkel tensor is the correct tensor to describe the gravitational influence of direct particle fields. This corrects an earlier calculation which had resulted in favour of the Frenkel tensor. The forms of the two tensors are examined in cosmological models with perfect future absorbers and imperfect past absorbers, and it is shown that only the canonical tensor is physically reasonable
