On the role of postulates in the understanding of Weyl gauge symmetry

Abstract: Understanding of Weyl gauge symmetry is rarely associated with underlying postulates. Here we show that such an omission leads to discrepancies in regard to the reach and consequences of gauge symmetry within gravitational theories. Replacement of the postulates which underlie the conventional approach, by just the opposite assumptions, leads to a radically different interpretation of Weyl gauge symmetry, which shares the same mathematical foundations and carries observational consequences.
