In this work, we analyze the role of general relativity (GR) in the dynamical properties of outer small body populations in systems that host an eccentric inner Jupiter-mass planet. We carry out two sets of N-body simulations, one of them only includes gravitational forces,while the second one incorporates GR effects. Our results suggest that GR can significantly modify the dynamic structure of the outer particles. On the one hand, if the GR is included in the simulations, the range of prograde (retrograde) inclinations of the nodal libration region is reduced (increased) respect to that obtained in absence ofGR. On the other hand, GR more efficiently suppress the inclination excitations and nodal librations for particles with large semimajor axes and low eccentricities.
