Combined Gravitational Action-Fourth Part: Exploitation

In previous papers [1,2,3] relating to the concept of Combined Gravitational Action (CGA) we have established the CGA-theoretical foundations as an alternative gravity theory that already allowed us to resolve -in its contextsome unexpected and defiant problems occurred inside and outside the Solar System like, e.g., the anomalous Pioneer 10’s deceleration; the observed secular increase of the Astronomical Unit [4]; the apsidal motion anomaly of the eclipsing binary star systems and the study of CGA-effects in the non-compact and compact stellar objects. All that has been done without exploiting fully the CGAformalism, hence, the main purpose of the present paper is to exploit profoundly the CGA-equations in order to investigate, among other things, CGA-spin-orbit coupling precession and application of CGA to Large-Scale Structures with the aim of resolving the problem of galactic rotation curves.
