In theoretical physics, a skyrmion, conceived by Tony Skyrme, is a homotopically non-trivial classical solution of a nonlinear sigma model with a non-trivial target manifold topology i.e. a particular case of a topological soliton.
In theoretical physics, a skyrmion, conceived by Tony Skyrme, is a mathematical model used to model baryons (a subatomic particle). A skyrmion is a homotopically non-trivial classical solution of a nonlinear sigma model with a non-trivial target manifold topology; i.e., a particular case of a topological soliton.
