Abstract
The soliton breathing mode is investigated in the framework of linear response theory within a Skyrme model vector meson stabilized. The effective Lagrangian considered includes the (introduced following the standard prescription of nonlinear chiral symmetry) and the mesons. The monopole response function is found to have a pronounced peak which is identified to the (Roper) resonance. The results are compared to those obtained within the local approximation.
