Bimetric Machian gravitation

On the basis of some previous papers a bimetric Machian approach to gravitation is proposed. Such an approach, besides being observationally distinguishable from bimetric Rosen's theory, differs from Rosen's approach mainly for its Machian behaviour and for its simpler mathematical structure. The two approaches supply approximately with the same experimental predictions, as the Schwarzschild-like problem is concerned. (author)
