abstract = "The expansion of both sides of Einstein's field equations in the
weak-field approximation, up to terms of order 1/c4 is derived.
This new approach leads to an extended form of gravitomagnetism
(GEM) properly named as Beyond Gravitomagnetism (BGEM). The metric
of BGEM includes a quadratic term in the gravitoelectric potential
n the time and also space metric functions in contrast with first
post-Newtonian 1PN approximation where the quadratic term appears
only in the time metric function. This nonlinear term does not
appear in conventional GEM, but is essential in achieving the
exact value of Mercury's perihelion advance as we explicitly show.
The new BGEM metric is also applied to the classical problem of
light deflection by the Sun, but the contribution of the new
nonlinear terms produce higher-order terms in this problem and can
be neglected, giving the correct result obtained already in the
Lense-Thirring (GEM) approximation. The BGEM approximation also
provides new terms that depend on the dynamics of the system,
which may bring new insights into galactic and stellar physics.",
