A note on post-Riemannian structures of spacetime
Abstract
Description
A four-dimensional differentiable manifold is given with an arbitrary linear connection $Γ_α^β=Γ_{iα}^βdx^i$. Megged has claimed that he can define a metric $G_{αβ}$ by means of a certain integral equation such that the connection is compatible with the metric. We point out that Megged's implicite definition of his metric $G_{αβ}$ is equivalent to the assumption of a vanishing nonmetricity. Thus his result turns out to be trivial.
