Erhard Scholz
H. Weyl's proposal of 1918 for generalizing Riemannian geometry by local scale gauge (later called {\em Weyl geometry}) was motivated by mathematical, philosophical and physical co…

A scalar field inducing a non-metrical contribution to gravitational acceleration and a compatible add-on to light deflection
Erhard Scholz
A scalar field model for explaining the anomalous acceleration and light deflection at galactic and cluster scales, without further dark matter, is presented. It is formulated in a…
