Fully Extended Quasi-Metric Gravity
Dag Østvang
The original theory of quasi-metric gravity, admitting only a partial coupling between space-time geometry and the active stress-energy tensor, is too restricted to allow the exist…
Birkhoff's Theorem for Quasi-Metric Gravity
Dag Østvang
Working within the quasi-metric framework (QMF), it is examined if the gravitational field exterior to an isolated, spherically symmetric body is necessarily metrically static, or…
Interpretations of Cosmological Spectral Shifts
Dag Østvang
It is shown that for Robertson-Walker models with flat or closed space sections, all of the cosmological spectral shift can be attributed to the non-flat connection (and thus indir…
Metrically Stationary, Axially Symmetric, Isolated Systems in Quasi-Metric Gravity
Dag Østvang
The gravitational field exterior respectively interior to an axially symmetric, metrically stationary, isolated spinning source made of perfect fluid is examined within the quasi-m…
Classical Electrodynamics in Quasi-Metric Space-Time
Dag Østvang
The quasi-metric manifold is equipped with two one-parameter families of metric tensors and , each parametrized by the global time function $…
Spherically Symmetric, Metrically Static, Isolated Systems in Quasi-Metric Gravity
Dag Østvang
The gravitational field exterior respectively interior to a spherically symmetric, isolated body made of perfect fluid is examined within the quasi-metric framework (QMF). It is re…
