Ghost free analysis of a nonsymmetric theory of gravitation

Abstract

The absence of ghost-negative energy radiative modes in a proposed generalized theory of gravitation based on a non-symmetric metric is reanalyzed. The missing contribution of the symmetric sector of the Lagrangian is calculated and shown to be null. The ghost free character of the theory is then firmly established.

Interior problem in a ponsymmetric theory of gravitation

“…The theory was shown to be consistent with the four classical tests of general relativity (GR). In [2] it was shown that the theory is definitely free of ghost-negative radiative modes even when expanded around a Riemannian GR background space. In a more recent paper [3] the conservation laws of energy and momentum were established.…”
