Analytical direct planetary perturbations on the orbital motion of satellites
(2013-01-01)
An analytical expansion of the disturbing function arising from direct planetary perturbations on the motion of satellites is derived. As a Fourier series, it allows the investigation of the secular effects of these direct ...

QCD phenomenology with infrared finite SDE solutions
(2009-12-01)
Recent progress in the solution of Schwinger-Dyson equations (SDE), as well as lattice simulation of pure glue QCD, indicate that the gluon propagator and coupling constant are infrared (IR) finite. We discuss how this ...

Reliability of the optimized perturbation theory in the 0-dimensional O(N) scalar field model
(Elsevier B.V., 2016-12-15)
We address the reliability of the Optimized Perturbation Theory (OPT) in the context of the 0-dimensional O(N) scalar field model. The effective potential, the self-energy and the 1PI four-point Green's function for the ...
On the straightforward perturbation theory in classical mechanics
(IOP Publishing, 2018-06)
We show that it is possible to extract useful information from the straightforward perturbation theory in classical mechanics. Although the secular terms make the perturbation series useless for large times, these expansions ...
