In this work we analyze the orbital evolution and the dynamical stability inthe vicinity of the small Saturnian moons Aegaeon, Methone, Anthe and Pallene.We numerically resolve the exact equations of motions to investigate theorbital motion of thousands of test particles within and near to the domain ofthe 7/6, 14/15, 10/11 mean motion resonances of Aegaeon, Methone and Anthe withMimas, respectively. We show that, for massless small moons, the orbits ofparticles initially restricted to the resonant domains remain stable for atleast $10^4$ yr. We also conduct numerical simulations considering Aegaeon,Methone, Anthe and Pallene as massive bodies. The results show that mostparticles undergo significant perturbations in their orbital motions,ultimately destabilizing in timescales of a few hundreds of years or even lessthrough collisions with the four small moons. In addition, we also simulate theorbital evolution of test particles initially distributed in form of arc aroundAegaeon, Methone and Anthe. We show that the initial arcs are dynamicallyeroded on timescales of hundreds of years, allowing us to constraint thetimescales for which gravitational forces operate to remove particles from theobserved arcs.
