The galactic dynamical system expressed by a third-order axisymmetric polynomial potential is investigated numerically by computing periodic solutions. We define as Sthe compact set of initial conditions generating bounded motions, and as S p , with

This paper presents the approximate general solution of the triple well, double oscillator non-linear dynamical system. This system is non-integrable and the approximate general solution is calculated by application of the Last Geometric Theorem of P

The general solution of the Henon–Heiles system is approximated inside a domain of the (x, C) of initial conditions (C is the energy constant). The method applied is that described by Poincare as ‘the only “crack” permitting penetration into

In this work, a numerical approach is presented for determining the longshore current modification caused by the presence upon the seabed (boundary) of a submerged groin system. This system consists of several low groins with one end-point inshore an

The submerged groin arrangement as a shore protection tool examined in detail by means of direct numerical integration by Kafousias et al, 2000, is examined in part I of this paper on the basis of the finite elements dynamic analysis in order to dete

The micro-scale dynamics of bedload transport in the surf zone with or without submerged groins placed on the seabed are discussed on the basis of flow energy dissipation using the analytical solution of the equation of flow within the boundary layer

Poincare's continuation method is applied to the elliptic restricted problem for the computation of four families of doubly symmetric three-dimensional periodic orbits emanating from similar orbits corresponding to zero eccentricity. The results are

This paper considers the two-dimensional hydromagnetic oscillatory flow of a viscous, incompressible and electrically conducting fluid, past a porous, infinite, limiting surface subjected to variable suction and moving impulsively with a constant vel

We consider a magnetic field that is a superposition of the field of a dipole and a uniform magnetic field, the latter directed parallel to the magnetic moment of the dipole. We study the form of the field lines of that field, and determine the allow

In the present work we study the equatorial motions of charged par ticles that are performed within a field consisting of the superposition of a dipole field—that could represent the magnetic field of a planet — and of a uniform magnetic field no
