Using numerical simulations we investigate topological charge N = 3, 4 soliton head-on collisions in the CP1 model on a flat torus T2. We observe dual-polygon scattering π/N except for configurations of three solitons starting far away from each oth

After an introduction of solitons with emphasis in elementary particle theory, we present a non-linear O(3) model in (2 + 1) dimensions modified by the addition of both a potential-like and a Skyrme-like term. We study some basic scattering propertie

We present our results of a numerical investigation of the behaviour of a system of two solitons in the (2+1) dimensional $CP^1$ model on a torus. Defined by the elliptic function of Weierstrass, and working in the Skyrme version of the model, the so

Using numerical simulations, the stability and scattering properties of the O(3) model on a two-dimensional torus are studied. Its solitons are found to be unstable but can be stabilized by the addition of a Skyrme term to the Lagrangian. Scattering
